system lockup - ata related and spurious interrupts

[Alexander Mueller]

> Hi all,
> Just today I saw the commitments to /dev/ata src for releng 5_2 and rebuild kernel ( custom ) and the system which was working fine for few days, lockup in a few hours with WRITE_DMA error on LBA XXX .. the disk is attached to ICH5 SATA controller and build raid with atacontrol ( but in bios raid its disabled ). As somewhere I saw , it's recommended to disable hyperthreading and now I am running with disabled. My mb is Asus P4P800 deluxe

> Hmm and I cannot boot it in verbose mode...
> it gives me millions of spurious interrupts on ata2 and ata3 controllers ...both with hyperthreadin on and off...

Hi Putinas,

I can't offer you any help but at least I can tell you that I'm
experiencing exactly the same two problems: TIMEOUT - WRITE_DMA
when hyperthreading is enabled and inability to reboot or power
off when hyperthreading is disabled. My hardware is similar to
yours: Asus P4C800E Deluxe with P4 3.0 GHz using the onboard
SATA controller integrated into the ICH5. My hard disk is a
WD Raptor 740GD. Currently nobody seems to take care of this
problem although there must be quity a lot of people out there
running into similar troubles.

Regards,
