IDE subsystem issues with 2.4.18/19

IDE subsystem issues with 2.4.18/19

[Dexter Filmore]

Got a motherboard with VIA VT8233 Southbridge (a MSI K7T266 Pro2), Slackware
8.1 with a standard kernel (tried .18 as well as .19) patched with SGI XFS
support, two atapi drives attached with /dev/hdc is Pioneer115 DVD and
/dev/hdd is a Traxdata 24x-writer, both running in scsi emulation.
Got VIA-support compiled in.

Everythings runs fine: reading DVD, reading CD, writing CD. 
*Apart from*: CD ripping. When trying to read audio CDs, the system locks up,
can't reproduce the exact error msgs right now, need a running system atm. If
you like, I'll post them later on.

Tried cdparanoia 9.8-III, cdda2wav - nothing works.

I contacted Vojtech Pavlik, the author of the via82xxx.c code who advised me
to ask Alan Cox or Andre Hedrick about this, so I thought best write to this
list.
Are there any workarounds/patches/voodoo magic for this problem?

I had the same problem on the same motherboard with a 
Goldstar LG DVD/CD-RW drive.  The Goldstar FAQ
(http://www.lgeservice.com/faqcdrw-1.html) mentions something about a 
problem with DMA on the VIA motherboard.

So on a whim, I tried a different CD-ROM, and it works perfectly.  Now I am using a ASUS CD-ROM for ripping audio, and my Goldstar for everything else, which seems to be a decent solution. 

So it would appear to be an interaction problem between certain CD drives and the VIA firmware, but I am not sure if a firmware update even exists, and if it does, I don't know if it will help or not (www.via.com.tw seems to be down right now).  I'm actually very happy with my current setup, and so I haven't been motivated to try anything new.

So, draw strength from the fact that you are not alone, but I can't offer you much more help than to tell you to swap out hardware.  Sorry.

    I have a VIA 586B, and I have the same problem with a LG CD-ROM
drive. Sometimes when ripping audio from CD's the drive seems to
'freeze'. The only solution is opening the drive and unloading the
modules. My Plextor CD-RW works OK in any condition ;))))

Hi, 

I don't know if it is related to this, but there seems to be general bug in 
the cdrom-ide driver to get the exact size of a CD.
When reading a CD-image using dd, my system also locks up until I eject the CD 
with the cdrom-drive-eject button.

I've already send the following patch to Jens Axboe, but so far he hasn't 
answered yet:

diff -rbBu linux-2.4.19/drivers/ide/ide-cd.c

        stat = cdrom_queue_packet_command(drive, &pc);
        if (stat == 0)
-               *capacity = 1 + be32_to_cpu(capbuf.lba);
+               *capacity = be32_to_cpu(capbuf.lba) - 1;

        return stat;
 }


Please note that I got the correct value of *capacity empirically, since I 
compered several values of the IDE-drive with the ones of my scsi drive. 

Since I don't understand the cdrom_read_capacity() function (would be nice if 
someone could explain me, where "capbuf.lba" gets its values and 
what be32_to_cpu() does), I'm not 100% sure that the patch is correct.

If it is "empirically" derived and reproduceble, I like it.
Especially when the theory people actually do it the empirical way.
