Description of problem:

I'm getting the following messages on two identical dual processor
opteron machines:

Version-Release number of selected component (if applicable):
kernel-smp-2.6.5-1.358


How reproducible:
Hard to trigger.  Might be related to having home directories NFS
automounted from a sever and having multiple logins happening quickly:

May 21 12:49:30 coop01 sshd(pam_unix)[26009]: session opened for user
orion by (uid=1744)
May 21 12:49:31 coop01 sshd(pam_unix)[26046]: session opened for user
orion by (uid=1744)
May 21 12:49:32 coop01 kernel: Badness in interruptible_sleep_on at
kernel/sched.c:1927

Additional info:

It doesn't appear to cause any problems, but kernel "Badness" is
worrisome!
