Thread-topic: Kernel Oops'
I'm having a kernel Oops occur when trying to rm or ls the directory:
/tmp/orbit-hengeje1
I can mv it to a different name.
After the mv it's automatically recreated, I can then and rm,ls,etc..
the recreated dir just fine.
However, I can not remove the renamed directory though - gets an oops
every time.

The first rm  -fr /tmp/orbit-hengeje1 will complete but message: "Can't
remove directory ... - (not empty)"
The second try of the command will hang and generate the Oops in the
syslog.
I guess its trying to tell me - If at first you don't succeed, don't try
again ;-)


Kernel versions and Oops'(direct from syslog):
