GA-MA790FX-DS5 SATA ahci NCQ erros on Jmicron 20360/20363 (JMB363)kernel 2.6.25-2 Debian/Lenny

[Sergey Spiridonov]

Hi

I got kernel errors [1] and [2] followed by SATA reset on heavy load on
the hard drive connected to the GA-MA790FX-DS5 onboard controller
Jmicron 20360/20363 (JMB363) (here is lspci [3]). Hard drive connected
to the another onboard (south bridge from AMD SB600) controller works
without problem.

I got two 1TB Seagate hard disks, ST31000340AS and ST31000340NS. I
connected one to Jmicron JMB363, another to SB600. After some testing
with several instances of bonnie++ I got kernel errors [1] and [2].
After this I exchanged hard disks connections. The one which was
connected to JMB363 I connected to SB600 and vs versa. Errors, timeouts
and hard drive resetting happened always on the hard drive which is
connected to the JMB363 (in log file it is sdb). There are no errors if
both drives are connected to the SB600.

Here [4] is complete (before i get errors) dmesg output after system is
booted.

I already replaced (took from working PC) power supply, memory, video
card and dvd drive. I get same problems also with this devices. So
problem must be motherboard, software or CPU. CPU seems to work O.K.

It looks like the problem is motherboard or ahci ata driver. Does
somebody have any clue about it? Is chip JMB363 broken or linux driver
is broken?
