It didn't help me :)

Axialys have a squid/socks/NFS server which therefore has a fair bit of
disk activity.

It died randomly a while ago, so I put a serial console on it and this
morning a coworker had to reboot it.

The last message was apparently the very same you are trying to prevent:
"hdg: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func only: 14"
(usual caveat about hand copied)

This was 2.2.17+ide (20000904)+RAID(2.2.17-A0).

This morning I updated to this patch and I tried to kill it just now.
It died :(
(That is with the 20001118 ide patch instead of the 20000904 one)

This time only with a "hdg: timeout waiting for DMA" with nothing
following it on the serial console.

It seems that
hdparm -t /dev/hde & hdparm -t /dev/hde & hdparm -t /dev/hde & hdparm -t
/dev/hde & hdparm -t /dev/hdg & hdparm -t /dev/hdg & hdparm -t /dev/hdg
& hdparm -t /dev/hdg
kills it in this way.  (That might be excessive but I'll get odd looks
is the proxy is down again because I'm testing exactly how many hdparms
it takes).

Let me know if there is anything I can test (in the evening/this weekend).
