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 09:06:42 mailstore2-1 -- MARK -- Sep 29 09:12:18 mailstore2-1 kernel: hdc: dma_timer_expiry: dma status == 0x20 Sep 29 09:12:18 mailstore2-1 kernel: hdc: status timeout: status=0xd0 { Busy } Sep 29 09:12:18 mailstore2-1 kernel: Sep 29 09:12:18 mailstore2-1 kernel: ide1: reset: success Sep 29 09:26:42 mailstore2-1 -- MARK --
Few more days of faithful service.

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