Subject: SATA disk reports DRDY and goes to PIO0 eventually. noapic fixes it
Since some time I noticed my nephew's Fedora 8 box would have
some noise in /var/log/messages with timeouts reported by the
SATA layer, with the drive in DRDY state. Flux is like this (from
the base Fedora 9 kernel installed today):

...and on and on and on.
Reading another report on lkml I turned to the ATA wiki @ kernel.org
today, as even the newest Fedora 9 update (2.6.25.3-18) was still
behaving the same way - pci=nomsi wasn't useful, acpi=off was
also not useful, noapic did instead get rid of the messages, even
under 'find /' (which would usually turn up the ATA resets in less
than 10 seconds).
Is there anything more useful than simply booting noapic that
can be done here, or is that it ?
Thanks,
