Hello guys,
I hope you've read my posting "DMA problem with ZIP drive and VIA VT82C598MVP
/ VT82C586B chip" (why does anybody answer?).
I now tried the 2.4.2-ac12 kernel including the latest VIA 82c586b driver
(version 3.21), but the effects were almost the same:
- just when the kernel tried to access to the hard disk during boot, DMA
errors were occured
- "hdparm /dev/hda" displayed 9 MB per second (and not 11 MB like without ZIP)
- /proc/ide/via reported 16 MB transfer rate (and not 33MB like without ZIP
drive)
- Kernel 2.4.2-ac12 reports a "ide-floppy: hdd: I/O error, pc = 5a, key = 5,
asc = 24, ascq = 0" error, 2.4.2 doesn't
My IDE configuration is:
/dev/hda: Hard disk => Primary IDE controller
/dev/hdc CD-ROM => Secondary IDE controller
/dev/hdd: ZIP => Secondary IDE controller
Could you please tell me whether it's a bug or a feature?
I'm really waiting for your answer - else I might get crazy with this problem
:-((
I attached both dmesg and /proc/ide/via, and my old posting.

OK. The ZIP drive can not handle uDMA, so it's normal for the secondary
controller to drop back. In my opinion, the primary controller should stay
at uDMA speed, but it is PC hardware so it is perfectly possible there is
something cheap that locks them together. I will bring up ac-12 and check
the error message...

Actually I'm beginning to suspect the PSU here ... does removing the
CD-ROM (leaving just the HDD and the ZIP in) help? Does the ZIP cause
errors even when connected just to the power cable (and not the IDE
cable)?

Do you mean the Power Supply Unit? Or the Program Storage Unit? ;-)
To answer to your questions:
- I haven't tried to remove the CD-ROM because both devices shall work
together
- the ZIP doesn't cause problems when just the power cable is connected
Although my PC has only got an old Baby AT 200W power supply I don't think
that's the point.

I don't see any other way how the ZIP could have impact on the IDE HDD
on a different IDE interface.
If you wonder why /proc/ide/via reports slower DMA rates for the HDD
when the ZIP is connected is because the auto slowdown code kicks in and
lowers the transfer rate when too many CRC errors happen.

The 82c586b can be a chip with locked-together IDE controllers, can't it?

Well, and what should I do now? I really need the ZIP drive.
Try without CD-ROM? Buy new ATX case with 300W power supply? And new
motherboard? And new processor? And ... and ... and?
Isn't there a chance to unlock the IDE channels (if they are locked)?
Remember, I've heard about a Windows patch to do this.
Paul, what did you find out?

Nasty chips whose two IDE channels aren't really separated. On one IDE
channel you either can use DMA or not. On these chips, switching off DMA
at the second controller also disables DMA at the first.

Yeah, Ok. My combination SHOULD work without any problems...
What else could I do? Swap CD-ROM and ZIP? Try new 2.4.2-ac14 with command
line parameters "ide0=dma ide1=nodma"?
