Subject: EXT4 panic at jbd2_journal_put_journal_head() in 3.9+
Date: Thu, 09 May 2013 07:59:30 +0000 (GMT) [thread overview]
Message-ID: <15102321.375241368086369792.JavaMail.weblogic@epml19> (raw)
Hello.
In my board, i ran the iozone with multi-thread option.
My board has 8 cores and i enabled CONFIG_SMP.
the iozone command as follow: iozone -l 20 -u 20 -r 64k -s 5m -o -F /user/f1 /user/f2 /user/f3 /user/f4 /user/f5 /user/f6 /user/f7 /user/f8 /user/f9 /user/f10 /user/f11 /user/f12 /user/f13 /user/f14 /user/f15 /user/f16 /user/f17 /user/f18 /user/f19 /user/f20
mount info as follow
cat /proc/mounts
/dev/sda3 /user ext4 rw,noatime,nodiratime,errors=panic,barrier=1,data=ordered 0 0
I got a message as below every time i ran iozone test.

When i ran without multi-thread option, the problem was not ocurred.
Thanks.
