Subject: reiser4 oops on unmount
Date: Tue, 24 Aug 2004 11:38:57 -0400 [thread overview]
Message-ID: <1093361937.12138.3263.camel@watt.suse.com> (raw)
Hello everyone,
I was testing reiser4 in the suse kernel and hit an oops during
unmount. This could be a problem with my local merge, but I wanted to
send here in case it is obvious.
The workload was create a few files and dirs, delete them, create 1
million files in a single dir, sync, unmount.
Unable to handle kernel NULL pointer dereference at virtual address 00000010
printing eip:
