Mozilla Freezes machine on RH9 / 8890

post #1 of 11

Thread Starter 
Has anyone encountered an issue using Mozilla on a sager linux installation ?
It's quite bizarre and I have no explanation... not all the time... but very frequently Mozilla crashes while loading a page and a kill -9 cannot even force the window shut. In fact sometimes it causes the whole machine to freeze. When the machine isnt frozen and I am able to bring up a shell and reboot, the Linux umount commands fail on the /home and /tmp and /swap partitions... says "device or resource busy"

Tried downloading the latest mozilla and the same problem ...

is it something in my kernel ? some compiler flags to pass to Mozilla on build ? what gives ?

please help . thanks

Hrmm - ok had a problem like this - turned out to be a network issue. Are you by any chance using a half duplex router/hub - or is you card only detection half duplex?. There is a bug in the driver for the gigabit network adapter that locks up linux sometimes when data is being sent out and received at the same time over a half duplex connection. My solution go buy a 100BT FD switch and havent had a problem since.

I was having this problem using my eth0 port connected to my Cable modem. Just yesterday I got a D-Link DWL G650 wireless PCI card up and running but the problem persists on this connection.
However maybe that's because (as far as I understand) the D-Link wireless card is somehow connected to Eth0 ? I dont understand it fully but I noticed on some setting for the wireless config that the wireless card had to be tied to an existing ethernet port , which in my case would be Eth0.

I dont see how buying a switch or a hub would help me here... but maybe loading a new or different driver for my ethernet port ???

thanks, I will investigate & report back... any other ideas or suggestions still welcome...

The wireless card should as a rule not be eth0 as that is already in use by your built in card. Generally wireless cards are wlan0/1/2 etc or eth1/2/3. If you are forcing it to tie to eth0 you may be causing problems.

Looks like a problem with JavaScript & Mozilla & Sager ? ?

Hey, My wireless card is eth1. I was only referring to a settingi which I saw when clicking on Edit of the wireless device under redhat-config-network . The screen reads like this :

Each Device needs to be attached to a physical device which can be selected below:
hardware device : [and a choice of eth0 - ethN ]
hardware: [same eth0 - ethN]

my settings now are hardware device : eth0 and hardware: eth1 .

BUT >>>>>> all this is irrelevant AFAIK . My net connection is working fine for SSH , FTP, and even web browsing in Opera. The only thing that causes the machine to hang is Mozilla, any version even Firebird, and seemingly it is happening when the page is trying to load some Java Script. Not Java. I have Java disabled. But Java Script. For example Yahoo Mail always crashes at the same place, after 3/4 of the page has been loaded.

I tried downloading the source and building it today but I got stuck because it says I am missing libIDL even though I have it but thats another trip....

So... any ideas as to why this can be happening ? It surely has to be some kind of issue between Mozilla and my Sager config because a problem of this magnitude would not make it into a final release of a software (if it was a bug) ...

sux big time to have to HARD REBOOT the machine every time I try to view a web page that has JS and disabling JS will just restrict me too much....

What video drivers are you running? I just udated mine to ati-drivers 3.2.8 ebuild and am experiencing the same thing. Of coure it's gentoo but might be something to consider. X is one of the few things that has direct access to the kernel. I'll try reverting back to an older set and see what happens.
EDIT
I just emerged the 3.7.0 drivers and it seems to have cured the mozilla locking for me. Check your drivers and see what happens. I was watching the ebuild progress and it takes the src rpm from RH and uses it as the source code. Give it a shot and see what happens.

BSmith, I am running 3.2.8's under Gentoo as well and am not experiencing any problems with Mozilla at all. This is really weird because the 3.2.8's are the stable ones while the 3.7.0's are the unstable ones. BTW, how are the 3.7.0's anyway? Better performance (*gears, etc)? Have you noticed any odd behaviour yet?

RH Freeze

Are u running fedora core ? I have seen so many guys in chat rooms complaning about the same problem. IT seems to be hardly tied to fedora build of the binary. HAve you tried downloading a BINARY of Firebird ( a tar.gz file, not a rpm ! ), untar and run directly the binary from that directory. If no freeze, then its Fedora core mozilla build causing problems. It is a good idea to run tail -f on /var/log/messages and tcpdump on 2 xterms just before and during making request in Mozilla request. that could help. Beware that mozilla is a shell script calling mozilla-bin ( or MozillaFirebird-bin ) so you should be grepping for the latter, ps aux should revel what is happening to mozilla procress during its execution.

Hope that helps to diagnose ur problem.

I'd love to give you info, but I shortly there after did an emerge -U world and every thing went south real quick. qt refuses to compile, so I'm trying to fix it now. world wants to update 168 packages. So it will be a while until it's back up. I'm actualy posting from the kids machine.

I've found portage behaving badly lately. From harmless-but-nevertheless-annoying warning messages regarding the portage tree at one point in time to it wanting to downgrade packages even though I emerge world with the upgrade-only flag as usual... something doesnt seem right. And the funny thing is that I mostly emerge only stable stuff and they consider these sort-of-beta releases stable.

thanks laclasse, Here is the stack trace ....

Hey Laclasse, thanks for the suggestions. I was looking in /var/log/messages before but not at the right thing. First thing I found was this message came up right before the crash:

Jan 18 12:22:02 localhost modprobe: modprobe: Can't locate module sound-slot-1
Jan 18 12:22:02 localhost modprobe: modprobe: Can't locate module sound-service-
1-0

The error which followed was the same as the one printed below.
I changed /etc/modules.conf to alias sound-slot-1 and sound-service-1-0 to the same as sound-slot-0.
That got rid of the above error message but the kernel still crashes with the message printed below.
Looks like it's some kind of sound issue. This error was coming up when I tried to open http://www.newbalance.com

any suggestions/advice most greatly appreciated. Just as a reminder: this is on a Sager 8890 3.2 Radeon 9600 (using fglrx 3.2.8) 512 MB etc etc... using alsasound drivers, which *are* functioning....
