IDE-CD and VT8235 issue!!!

IDE-CD and VT8235 issue!!!

[AnonimoVeneziano]

    Hi, I have this chip on a MSI KT4 Ultra (KT400 and VT8235) and an 
Athlon 2400+.

I have noe the kernel 2.4.19 and all works fine, but 2.4.19 don't 
support this chip (so no DMA & Co) and I've decided to upgrade to 2.4.20 
to get it working.
I've compiled in the Debian Way ( kernel-package) and installed the 
kernel, then I've rebooted it.
During the startup progress it have initialized the HDs fine , but when 
he had reached the first CDROM ( a NEC DVD READER) it locked up with 
this message:

hdc: DMA disabled
hdc: drive is not ready for command
ide1: reset: success!

and it repeats this messages in an infinite loop , I don't know how to 
solve this , there isn't a patch or something else?

The kernel that I've tried (without success) are:

kernel 2.4.20 (original)
kernel 2.4.20 -ac2
kernel-source-2.4.20 package by debian + patches
kernel-2.5.50-ac1(doesen't boot)
kernel-2.5.53 (doesen't compiles)

Please help

Thank u

Hi!

Same problem here. I have addressed this issue several times...so far no 
solution.

My specs:
MSI KT3 Ultra2 (VT8235)
TOSHIBA DVD-ROM SD-M1302
YAMAHA CRW8424E

Kernel 2.4.19:
The one I'm currently using. It doesn't detect the VT8235 and therefore 
I have no dma. But I can access/mount my DVD without a problem.

Kernel 2.4.20:
Detects the VT8235 at boot but hangs with my DVD Rom (hdc) --> doesn't 
boot. I have posted my problem here an Alan Cox suggested that I should 
try the -ac tree.

Kernel 2.4.20-ac2:
Some improvements - It detects the VT8235 at boot, also my DVD and CDRW. 
It boots fine and I have DMA on all my discs. But as soon as I try to 
mount a CD/DVD (mount /cdrom) the system hangs and I get this:

hdc: status timeout: status=0xd1 { Busy }
hdc: status timeout: error=0x60LastFailedSense 0x06
hdc: DMA disabled
hdc: ATAPI reset timed-out, status=0x80
hdd: DMA disabled
ide1: reset: success
hdc: status timeout: status=0x80 { Busy }
hdc: status timeout: error=0x01IllegalLengthIndication
hdc: ATAPI reset timed-out, status=0xd1
ide1: reset: success
hdc: status timeout: status=0x80 { Busy }
hdc: status timeout: error=0x01IllegalLengthIndication
end_request: I/O error, dev 16:00 (hdc), sector 0
hdc: status timeout: status=0xd0 { Busy }

and so on...

My guess is the DVD-drive. I know many people with the same southbridge 
(VT8235), who have dma since 2.4.20 an no problem at all at boot-time 
or mounting a CD/DVD.

Any hints?

Patrick

You're not alone with this problem. I suspect some fishy stuff in the
vt8235, because the driver programs it exactly the same as vt8233a, but
while the vt8233a doesn't seem to have problems with DVDs and CDs, the
vt8235 fails for many people.

It might be some new DVD drive, though.

Can you send me 'hdparm -i' of the drive?

I'll try to make a patch to circumvent the problem ...

Thanks.

Here the hdparm -i of my first ATAPI drive.

I don't know if my Cd-recorder have the same problem, It have never 
tried to initialize it.

Wow, that was fast.

The patch works perfect. The kernel boots with no problem, I have dma on 
all my disk AND I can mount a CD/DVD without any problems.
Would be cool to see this patch included in the 2.4.21 kernel.

Thanks,
Patrick

The lattest workaround from Vojtech fixed the problem for you ?
