Thanks for posting this Eldad, I had the same problem and this saved lots of trial and error!!
As an FYI all I did was exchange my ASUS A7V600 with an ASUS A7V600-X. Maybe the BIOS changed version, maybe the chipset is different - not easy to tell. Since I boot from my SATA drive this was quite troubling. Luckily I still had an old 2.6.6 kernel.
I had to revert back to a 2.6.6 kernel, 2.6.7 wouldn't work.
Jeff (or whoever) I too would be happy to help debug if there's anything I can do.
I can't check the exact failure point for a week (away from the machine) but here's the relevant bit of the dmesg (admitedley from a good booting kernel with APIC_IO set) showing (simulated) the point where the failure occured: libata version 1.02 loaded. sata_via version 0.20 ACPI: PCI interrupt 0000:00:0f.0[B] -> GSI 20 (level, low) -> IRQ 20 sata_via(0000:00:0f.0): routed to hard irq line 0 ata1: SATA max UDMA/133 cmd 0xB400 ctl 0xB002 bmdma 0xA000 irq 20 ata2: SATA max UDMA/133 cmd 0xA800 ctl 0xA402 bmdma 0xA008 irq 20 ata1: dev 0
After I get back on 19th Dec I'll be happy to try additional tests, provide additional info etc if anyone asks.
