A few days ago I turned on lm_sensors so that the CPU fans would run 
quieter.  Ever since then, Firefox has been crashing.  I upgraded from 
1.04 to 1.06 thinking it was a bug, no change.  I wiped my .mozilla 
directory and started fresh, still no change.  If I disable lm_sensors 
and reboot, everything is fine.  If I re-enable lm_sensors, Firefox 
starts crashing again.

Unfortunately, when Firefox crashes, there is no error message reported. 
  Even when I run it from xterm so that I can see any console output, 
Firefox will just vanish from my screen and not an error is to be seen.

I would love to be able to use lm_sensors with my system... any ideas 
what this could be?

ASUS K8N-E Deluxe Motherboard.
AMD Athlon64 3000.
Red Hat's Fedora Core 4 (64-bit)
Firefox 1.04 and 1.06 (32-bit so I can use flash)

Regards,

Michael.

Interesting..  Any messages in the log before or after lm_sensors?   Any
errors installing Firefox?    FC4 release notes about Firefox?   I found
FC4 x86 a challenge because it uses GCC 4.0 and some binaries were
incompatible.

Okay, I did that and ended up with a 36 kb log file but I can't make 
heads or tales of what it is indicating to me.  :-(

I haven't found any reference in release notes or by searching the web 
and the newsgroups on this.  Lucky me gets what appears to be a unique 
problem!  Firefox didn't report any errors installing, and lm_sensors 
does not report any errors loading.

I did uninstall the 32-bit version and install the 64-bit version of 
Firefox, and it runs fine with lm_sensor and cpuspeed active.  I removed 
the 64-bit Firefox and put the 32-bit back in, and the problem re-occurs.

I've switched of lm_sensors and cpuspeed again, for now, but would 
really love a fix for this.

Regards,

Michael.

No offense but the problem sounds like the 32-bit Firefox doesn't play
with the lm_sensors and I think the reason is the Flash player.    There's
no 64-bit Flash so it's compiled with GCC3.x and maybe there's some
proprietary Macromedia code that goes deep end on the 64-bit platform. 

I think in your  $ strace firefox  output you're looking for SIGINITs and
-1 errors.    man strace cause I'm No Expert

see why it's crashing. what are the last 20 or so lines?
