Hm, that's bad.

It might be caused by the scsi changes in -mm.  I assume that
2.6.12-rc6 does not exhibit this bug?

I'm about to disappear for 3-4 days - please remind me to
look at this if it seems that I've forgotten ;)

If you can do a bisection search through the patches in -mm that
would help.  I'd amek the first pivot point be around git-scsi-misc.patch.

Comment 4 Greg Kroah-Hartman 2005-08-10 13:41:13 UTC

If you disable preempt, does that help?

And this doesn't occur on 2.6.13-rc6, right?

Comment 5 Sharyathi 2005-08-11 07:47:17 UTC

   I looked for 2.6.13-rc6 and this panic doesn't occur for this.
But for 2.6.13-rc5-mm1 I tried to build with CONFIG_PREEMPT disabled still it
gets into panic.
  I will attach the Console output with preempt disabled

Is this still an issue with latest -mm tree ?
Otherwise, can we close it ?

Comment 8 Sharyathi 2005-10-10 22:43:56 UTC

Its not observed in the latest kernel 2.6.14-rc2-mm1 and  2.6.14-rc2-mm2 kernels

Comment 9 Stephanie Glass 2005-10-11 04:58:00 UTC

Closing bug since you no longer can reproduce.
