Subject2.4.0-test3 RAID lockup
From
Date
I'm not on linux-kernel so any Cc:s are welcome.

Russell Coker reported last Sunday, Jul 2, about the RAID-1 lockups
he has experienced. I have also experienced similar lockups with a
three disk RAID-0 setup. The disks just stop working and every
process that touches them goes to an unkillable state. Commands
like sync or reboot -f just freeze and do nothing. /dev/hda which
is not part of RAID works normally. The only way to reboot is to
press the reset button.

Disks hdc, hde and hdg are identical 17 GB Seagate disks with only
one, whole disk sized partition with id 0xfd. The machine has Abit
bp6 motherboard with two 433MHz Celerons and 256MB of memory. The
filesystem on /dev/md0 is reiserfs. The kernel is
linux-2.4.0-test2.tar.gz, patched with test3-pre1.gz and
linux-2.4.0-test3-pre1-reiserfs-3.6.10-patch.gz

The lockups have happened with heavy outbound rsync activity, 5
rsyncs pulling files over a switched 100Base-T ethernet or when
the machine has been doing a single rsync against a 600MB
CD image file on another machine. No modules were in use during
the lockups.
