Subject: Oops on blktrace
Date: Wed, 30 Dec 2009 01:41:02 +0000 [thread overview]
Message-ID: <20091230014102.GA7296@hostway.ca> (raw)
Hello,
I just experienced an Oops while running blktrace on a 2.6.30.9 kernel
(production system). There was no camera handy and no serial console
or crash dump log, so all we could get remotely was a function backtrace
copied by hand:
memset_c
relay_open_buf
relay_open
do_blk_trace_setup
blk_trace_setup
disk_name | HEX/HEX
blk_trace_ioctl
find_get_page
blkdev_ioctrl
filemap_fault
unlock_page
__do_fault
block_ioctl
vfs_ioctl
do_vfs_ioctl
sys_ioctl
system_call_fastpath
At the time I had just run "blktrace /dev/etherd/e10.1" (an AOE device),
having recently run "btrace -t /dev/etherd/e10.1" and similar with no
problem. I've since tried to reproduce this crash to no avail. Have
there been any similar experiences or related fixes since 2.6.30.9?
Cheers,
Simon-
