Comment 1 Chuck Ebbert 2008-09-25 02:46:00 UTC 
                        BUG_ON(signr != SIGKILL);

That's a new one.
Comment 2 Roland McGrath 2008-09-25 07:47:43 UTC 
"under load" does not constitute a recipe for reproducing a bug.
Please supply an actual bug report.

It would also be helpful to know if you see any similar problem with the f10/rawhide kernel.
Comment 3 H.J. Lu 2008-09-25 17:02:00 UTC 
It happened on 2 quad-core machines when I was running
gcc 4.4 "make check -j4" targeting Intel AVX emulator.
Kernel 2.6.25.14-108.fc9.x86_64 has no problems. Kernel
panicked at different places each time.
Comment 4 H.J. Lu 2008-10-01 21:04:28 UTC 
I tried kernel-2.6.27-0.372.rc8.fc10.x86_64 on
Fedora 9. My machine has Intel 82566DM-2 Gigabit
and Intel 82541GI Gigabit. The e1000 driver in
kernel-2.6.27-0.372.rc8.fc10.x86_64 doesn't see
82566DM-2 Gigabit. My machine needs 2 NICs.
Comment 5 H.J. Lu 2008-10-01 21:09:39 UTC 
82566DM-2 seems to need the e1000e driver. For
some reason, it isn't loaded under kernel
2.6.27-0.372.rc8.fc10.x86_6.
Comment 6 H.J. Lu 2008-10-01 21:13:07 UTC 
kernel-2.6.27-0.372.rc8.fc10.x86_64 doesn't have the e1000e
driver.

The e1000e driver is disabled in kernel-2.6.27-0.372.rc8.fc10.x86_64
due to overwriting data in the EEPROM of Intel's network chip. I guess
can't use it on my machine.
Comment 8 H.J. Lu 2008-10-03 22:40:40 UTC 
kernel-2.6.27-0.382.rc8.git4.fc10.x86_64 works fine
under the same load.
Comment 9 Chuck Ebbert 2008-10-24 02:37:21 UTC 
Please test kernel-2.6.26.6-79.fc9
Comment 10 H.J. Lu 2008-11-01 12:00:05 UTC 
kernel-2.6.26.6-79.fc9 is OK.
