hi,
running the strace_test from ltp 20080229 (ltp.sf.net) gives me
two different oopses, so far i was not able to pinpoint to a specific
testcase (propably because the strace uses the rng to decided what fails
and what not) one oops is in iret_exc(), the other in __copy_from_user_ll()
The oopses dont happen with 2.6.24 so this appears to be a regression, i am starting
a git-bisect, but this might take some time
Here is a full dmesg with the oopses happening, it usually takes less than a minute
until they trigger, strangely they dont appear in /var/log/messages, only on the netconsole

to be guilty. After reverting this manually (didnt revert cleanly)
i was unable to reproduce the oopses

Hi Eric,
This appears to be caused by init_fpu() missing from the
restore_sigcontext->restore_i387->restore_fpu_checking code path.
I believe that moving the init_fpu() call from math_state_restore to
restore_fpu_checking should fix the problem?
Regards,
Frederik

thanks Eric and Frederik for tracking this down. Eric, does Frederik's
patch fix the problem for you?

didnt have a chance to test this yet, I'll be back home tomorrow and
test Frederiks patch.

sadly the patch does not work for me :( I still get the oopses. I am
running this on a 32 Bit CPU, so arch/x86/kernel/traps_64.c doesnt get
compiled. I tried removing the same part from traps_32.c but then
the kernel oopses before netconsole is active.

I run that &$#@! intuitive test for an hour know with no effect. Can
you please provide your .config file ?

Appended patch should fix it. Eric, can you please check if it fixes the issue?
I have to fix the math-emu aswell. But I will send a different patch for it.

[patch] fix fpu restore during sig return
If the task never used fpu, initialize the fpu before restoring the FP state
from the signal handler context. This will allocate the fpu state,
if the task never needed it before.

running the test for 20 minutes now, no oops seen so far, seems to be
the right fix.

Suresh,
looks good. Applied to x86.git. Waiting for Erics confirmation.

i have been running the test now for ~4 hours, did reboot inbetween
twice and the oops didnt happen again, usually it occured in less
than 5 minutes, would say the patch fixed it.
