Description of problem: I received several kernel bug syslog messages while testing rawhide from April 27th. For example: Apr 29 12:38:07 bruno kernel: BUG: at kernel/fork.c:994 copy_process() Apr 29 12:42:04 bruno kernel: <3>BUG: sleeping function called from invalid context at kernel/rwsem.c:20 Apr 29 12:54:14 bruno kernel: BUG: at kernel/fork.c:994 copy_process() Apr 29 12:57:43 bruno kernel: BUG: at kernel/lockdep.c:1858 trace_hardirqs_on() Apr 29 13:07:24 bruno kernel: BUG: unable to handle kernel paging request at virtual address e88df00c Apr 29 13:07:28 bruno kernel: <3>BUG: sleeping function called from invalid context at kernel/rwsem.c:20 Apr 29 13:13:32 bruno kernel: BUG: unable to handle kernel NULL pointer dereference at virtual address 00000000 Apr 29 13:17:15 bruno kernel: BUG: at kernel/fork.c:994 copy_process() Version-Release number of selected component (if applicable): 2.6.20-2925.5.fc7xen How reproducible: Unknown Steps to Reproduce: 1. I don't know. 2. 3. Actual results: Kernel bug syslog messages Expected results: No kernel bug syslog messages Additional info:

The Oops looks like bug #234008. Could you confirm if the problem is gone with a newer kernel (the latest kernel on either FC-6, F-7 or Rawhide).
I tried 2.6.20-2936.fc7xen and didn't see the problem. The string 'BUG' did not appear in the syslog entries from the boot and for the short (a couple of minutes) I was running with this kernel nothing odd happened. I tried it on the same machine as I had previously had the problem on.
