I removed the ATI Radeon AGP card from my machine and reverted to the onboard i915 Intel video and no more problem. I think there may be something not quite right with the Xorg Radeon driver (or is it the radeon.ko?), or maybe even the hardware itself as what finally prompted me to remove the card was that I began to see more and more artifacts on the display - at its worst, my white-background xterms were becoming unreadable due to a growing reddish tinge that could only be cured by 'wiping' one xterm with another!

1. If I were you, I'd go for the safer path and assure myself that I
don't use a system (OS & apps) built with unusual compiler flags.
2. Try to use a pre-built Ff package from ftp.freebsd.org and see if
the problem still occurs.
3. Actually, to get a core file, the steps are:
- as a regular user open a console, make sure you are in a directory
with write permissions (${HOME} is ok) and launch firefox
- open another console, note the pid of firefox-bin and type the above
command (gdb /path/to/ff-bin pid) but don't press Enter yet
- try to fry the CPU again. If succeeded, press Enter in the gdb
console and get a full backtrace.
- alternately, if you can't attach to the process, try to send SIGABRT
when it goes crazy.

You should also consider rebuilding Firefox without optimizations.
Trying to use compiler optimizations for Gecko-based applications is the
perfect recipe for trouble :)

Yes, this problem seems to have begun after the upgrade from 6.1-RELEASE to 6.1-RELEASE-p1, though it's hard to see the connection. > >Try to reproduce the above described behaviour and jump over with gdb. >Sort of: > >gdb /usr/X11R6/lib/firefox/firefox-bin >(... wait) >(gdb) t a a bt full Excuse my ignorance - I take it I need to o start firefox normally o run gdb as above o invoke the crash situation o then ... ?

Hi Joel, I tried to reproduce it on two 6.1-STABLE systems but with no result, file upload works just fine. I have a bad feeling that it's very hard to reproduce. On the other hand, did the problem started to occur at a specified date? Can you link the problem with a world / ports update? However: > I'd appreciate any tips for diagnosis/recovery.
