Subject: Badness in as_completed_request
Date: Wed, 5 Nov 2003 00:58:17 -0800 [thread overview]
Message-ID: <20031105085817.GH21853@vitelus.com> (raw)
I've been seeing this about every day for the past month or so, while
tracking 2.6.0-test*. Usually by the time I feel like reporting it I'm
a few revisions behind and decide to upgrade before complaining about
it. Now I'm running -test9 and it still happens. This happens every
few day or so under normal load and every few minutes under high I/O
load. I'm running an x86 system with a 3ware RAID5:
