Hello Martin,

M> ad0: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=226025086

Yeah, I updated and rebuilt on seeing your email, but found it did
little.  I has TIMEOUTs again within 10 minutes of rebooting.

I'd certainly be interested in hearing about your results, but from
the general lack of discussion of the problem on this list, I'm
guessing we may be on our own. I'm not sure anyone is actually working
on a "fix", because I'm not sure the problem is recognized.

I have two separate Intel IHC5 based boxes affected by DMA TIMEOUTS,
both with SATA drives and I'd like to get to the bottom of this.

Regards,

Tony.
