Subject: 2.6.19-rc3-git7: BUG: mutex warning sysfs_dir_open
Date: Tue, 31 Oct 2006 12:19:51 -0500 [thread overview]
Message-ID: <454785B7.3040600@rtr.ca> (raw)
I don't know if the kernel is getting better at detecting its own bugs,
or if 2.6.19 is shaping up to be the flakiest kernel in recent memory.
I found this in my syslog just now:
