Not a regression as it seems this user's box has always been broken. I've
been running heavy testing with 2.6.22rc6 and IT8212 and its working
reliably for the "dumb" mode in question.
The hardware mode needs a fix Tejun has queued somewhere (probably in
Jeff's vast backlog) and then works too.
I'm not even sure this report is IT8212 related rather than just an IRQ
storm
Hello.

Ugh, 0xa0 is the device/head register's value, not the status register's!
I'd suppose that I/O space was borken in some funny way, however, it would be
hard top expect form x86 which should be prone to endiannes blues...

Why does the driver report "irq 0"?
ata7: PATA max UDMA/133 cmd <blah> ctl <blah> bmdma <blah> irq 0 <====
Above that, the ACPI layer says it assigned IRQ 20

I removed this bug from the kr list.

Because the libata core code in 2.6.22rc6 reports all the ports and IRQ
values wrongly ?

AFAIK that was fixed, for IRQ. Please point out examples where it
remains broken...

2.6.22-rc6 it is broken, for all the systems I've looked at, as are the
port numbers. Tejun posted fixes for the IRQ but they do not seem to have
been applied, or if they were it was post -rc6 to a git tree.

I've seen the patch that eventually became
22888423b3b1b96573250671afb5b72ea4364902 from Olof Johansson but nothing
from Tejun on the subject.
