Subject: disk I/O hang in 2.6.0-test4-mm5
Date: Thu, 4 Sep 2003 10:16:26 -0700 [thread overview]
Message-ID: <20030904171626.GA26054@osdl.org> (raw)
I'm seeing a mkfs.ext2 that never completes under 2.6.0-test4-mm5.
I ran 4 mkfs.ext2's concurrntly, each on a seperate partition on the
same disk. Three of the completed. Here's the sysrq stack trace from
the one that didn't.
This doesn't occur on mm4.

This is on a system with a DAC960 driver. But we've seen it here
on a system with scsi disk as well.
