Hi All

   Motherboard: ASUS P5VD2-MX SE
    (BIOS 0602)
   DVD: TSSTCorp SH-S128D
   Hard drive: 320GB SATA1 Maxtor STM33320820AS
   Pentium(R) D CPU 3.20GHz, Cores: 2
   Linux 2.6.22.13-0.3-default x86_64
   System: openSUSE 10.3 (x86_64)
   KDE: 3.5.7 "release 72.2"
   Model: GeForce 7300 GS

I've recently upgraded to 10.3 with a full/new install from a previously
fully functional 10.2 (no hardware changed during the upgrade).  I'm now
getting a significant run of "ata3.00:exception Emask 0x0 SAct 0x0 SErr
0x0 action 0x2 frozen" error messages.

The effect is such that, for example, if I don't start VirtualBox
immediately, after booting the system, it just hangs ...

The relevant part of dmesg are (with multiple occurrences of):

"
ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen
ata3.00: cmd a0/00:00:00:00:20/00:00:00:00:00/a0 tag 0 cdb 0x1a data 255 in
         res 40/00:03:00:00:00/00:00:00:00:00/a0 Emask 0x4 (timeout)
ata3: soft resetting link
ata3.00: configured for PIO0
ata3: EH complete
"

plus, the occasional:

"
sr0: CDROM (ioctl) error, command: Test Unit Ready 00 00 00 00 00 00
sr: Sense Key : Aborted Command [current] [descriptor]
sr: Add. Sense: No additional sense information
"

The configuration for the drive starts with "UDMA/33" and slowly
deteriorates to "PIO0".

Following one prompt, in dmesg, I tried editing /etc/smartd.conf to
uncomment "/dev/sda -a -d sat".  But no luck ... the "frozen" message
continues ...

I've done a major Google around this topic and can find no obvious
consistency with the potential cause or solution; it appears independent
of hardware/software/Linux version/drivers/...  I initially though the
problem was with EXT3 journalling (as the impact appears to increases
over time - but I cannot fathom how to force a check of EXT3 at boot).
If I try to run "Repair Installed System", from the original
installation DVD, it just reboots ...

I'm lost for a solution ...

Further information: "/sbin/lspci | grep IDE" gives:

"
00:0f.0 IDE interface: VIA Technologies, Inc. VT8237A SATA 2-Port
Controller (rev 80)
00:0f.1 IDE interface: VIA Technologies, Inc.
VT82C586A/B/VT82C686/A/B/VT823x/A/C PIPC Bus Master IDE (rev 07)
"

Has anybody solved this for OpenSUSE Linux 2.6.22, or can help me
investigate it further ...

Cheers
