SubjectCMD680, kernel 2.4.21, and heartache
From
Date

Hello,

I've got a Big Problem.

Day 0: 8 new NFS servers go online, they are P4-2.4GHz boxes with two each
120GB Samsung drives attached to CMD680/SiI680 IDE controllers. They run
Debian stable on a 2.4.21 kernel, with SMP enabled though they are uniproc
boxes, running NFSv3-via-TCP and reiserfs. CMD680/siimage support compiled
in, obviously. Software RAID, mirroring drives.

Out of 8 boxes:

*) One has crashed hard. I'm about to drive to the datacenter to plug in a
KVM and take a picture.
*) Three have had DMA turned off and have given extremely spooky errors.
Read below.

Some factors that are definitely NOT a problem:
- Faulty run of drives. This has also happened to Hitachi 80GB drives in the
same configurations.

- Heat. They're in a chilly room. The cases haven't overheated. We've had
guys checking this every few hours after the first one went bonkers.

Possible problems -
- Simple software problem that somebody can fix and save the day. :)
- All Dell Poweredge 650 servers are broken. :/

Days 1-6: Faithful service.

Day 7:

Sep 29 09:12:18 mailstore2-1 kernel: hdc: dma_timer_expiry: dma status == 0x20

I'll post again when I've got the text of the kernel panic.
