Subject: scsi-misc crash - WARNING: at fs/sysfs/dir.c:487 sysfs_add_one+0x150/0x180()
Date: Fri, 04 Dec 2009 11:27:55 -0600 [thread overview]
Message-ID: <4B19469B.6000009@sgi.com> (raw)
This is with scsi-misc pull from a couple days ago. kernel is rc5 based.
(I added the kdb patches....)
I'll see what I can see with this, but thought I'd post here in case
someone else has fix / suggestions.
