Subject: BUG: soft lockup detected on CPU#1!
Date: Tue, 10 Feb 2009 23:16:25 -0800 (PST) [thread overview]
Message-ID: <407126.80177.qm@web30205.mail.mud.yahoo.com> (raw)
Hello,
I am running the 2.6.28 based xfs kernel driver on a
custom kernel with following kernel config enabled.
CONFIG_PREEMPT
CONFIG_DETECT_SOFTLOCKUP
Running the following xfsqa causes a soft lockup. The
configuration is a x86 with Hyperthreading, 4GB RAM
and a AHCI connected JBOD. Its 100% reproducible.
Any suggestions/inputs on where to start debugging the
problem would be much appreciated.
