[2.] Full description of the problem/report:
Been having problems with the AHCI driver for this new server for quite
some time now, it slowly seems to be getting better as the version
numbers increase (2.6.15 seemed fine, though I didn't test much,
2.6.1[7-8] was unusable, 2.6.20-rc6 seems nearly perfect) but I still
see some errors appearing on the system. I have swapped disks in the
system and I see the problem with 3 different systems (all identical)
and 3 different sets of disks.
This is the error message that appears:
