G'day all,
This has been happening on a lightly loaded box for a while now. I have
posted about it before.
The issue is now I've upgraded 3 drives from 250GB Maxtors to 750GB
WD's, it's just getting worse, particularly when the drives are loaded.
Oh, I forgot, I still have the problem where I can't shut the box down. The SCSI layer tries to sync
cache on the drives, the 1st one errors out, and when the controller tries a hard reset on the port
the box locks hard requiring a hard poweroff or a hard reset. (No serial console, sysrq, NMI oopser
or anything else works)
I have 2 boxes with sata_promise controllers and they both do this. Not surprising given they are
both running late kernels (> 2.6.20) and both have almost exactly the same hardware in them.

exactly the same thing on both boxes).
I've played with options to halt and all the other things I can think of. I just can't get it to
shut down cleanly and all 15 drives go *clunk* when I have to hard power off the box. Normally this
is not an issue as it happens once or twice a year at most, but recently I've been doing some server
room reconfiguration and have had to do a number of power cycles. Nothing like 30 drives across 2
machines going *clunk* to make your stomach turn.
