VIA vt8235 headache

VIA vt8235 headache

[Petr Sebor]

Hello,

since after the hw update to VIA KT400 board (MSI KT4 Ultra) I am having
a problem where I can't access any devices hanging on the secondary IDE1
channel (hdd & cdrom) The hardware does work ok on the 'other' OS
though...

This is going on on 2.4.20, 2.4.21-pre4, 2.4.21-pre4-ac1
and 2.4.21-pre4 + the patch Andre is having on kernel.org:

The timeouts takes ages... but it will eventually boot. I can't however 
access
anything on IDE1, this will result to another timeout round with no success
at the end.

If I physically remove the /dev/hdc (Quantum Fireball disc), I am 
getting just
this from the cdrom:

hdd: set_drive_speed_status: status=0x7f { DriveReady DeviceFault

hdd: irq timeout: error=0x00
hdd: DMA disabled
hdd: ATAPI reset timed-out, status=0xd1

I'd be pleased if someone could enlighten me a little bit...

Thanks,
Petr

If you remove just the DVD drive what occurs ?

Also do you have ACPI support enabled, as that breaks a lot of systems

The more reports I get the more i think this is a vt8235 hw-bug. Or
the vt8235 registers are different from all its predecessors.

I'll send a patch soonish to fix this. (it's the address setup
timing - it must be set to 0xff on a vt8235 or problems happen with
ATAPI devices).

With the cdrom removed I am getting nice clean boot with
no timeouts, errors or lost interrupts:

...but when trying to actually mount the disk, I'll get this:

hdc: DMA disabled

hdc: lost interrupt

... and the mount fails.

 >>Also do you have ACPI support enabled, as that breaks a lot of systems

ACPI was enabled, but disabling it (recompiling with ACPI disabled)
does not have any effect.

I am still unable to access the disk on IDE1 even with the cdrom
removed on that channel. (though from the dmesg it looks like the
cdrom makes things even worse)

I have also tried Alan's new 2.4.21-pre4-ac2 (btw: extraversion is
still -ac1), with no difference.

I am looking forward to try the patch!

Best regards,
Petr

hi petr,

i had the same errors (although i never experienced any issues with hd,
but this seems to be because i'm running them on primary while having my
atapu devices on secondary). i fixed them the following:

- using 2.4.21pre4 (pre3 worked either)
- applying the following patch from vojteck:

<--
ChangeSet@1.884, 2002-12-19 11:23:11+01:00, vojtech@suse.cz
    VIA IDE: Always use slow address setup timings for ATAPI devices.

Hi,

with this patch applied over the 2.4.21-pre4-ac2, the CDROM on IDE1 now
works ok, no more error messages.

The harddrive on /dev/hdc is still choking though...

hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdc: dma_intr: error=0x00 { }
hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdc: dma_intr: error=0x00 { }
hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdc: dma_intr: error=0x00 { }
hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdc: dma_intr: error=0x00 { }
hdc: DMA disabled
ide1: reset: master: error (0x00?)
hdc: lost interrupt

Regards,
Petr
