[FREEZE] 2.4.19-pre10 + Promise ATA100 tx2 ver 2.20

[Fabio Massimo Di Nitto]

Hi all,
            probably was already discussed (I hope not).

I get a really bad freeze when there's heavy writing over the 2 x 120GB 
WD disks.
reading seems to be ok.

Since Im really not an expert in setting up IDE stuff the only things I 
can say is that
there's no OOPS or error or nothing on the screen/log.

The freeze is reproducible both with 2.4.19-pre10 and 2.4.18.
In my config I have tryed with/without DMA/Promise special options and 
different combinations
of them with no results.

I will be glad to offer more info and help if someone can kindly tell me 
how to debug
this. If it's needed I can consider providing access to the machine.

Thanks
Fabio

Those have no effect in 2.4.19-pre10 and a few earlier pres; I don't
remember the exact number.

Does the machine recover from the freeze or do you have to reboot?

I have to hard reset the machine. Keyboard is unuseable at that stage.
not even Magic sysreq works.

Are you running X? If yes, try reproducing the error while at a text
console. It's possible some panic message will make it that far. Messages
from a dying kernel will often not make it into the syslog.

Unfortunatly there's no X and no space to install it. That box should be 
my home
(read: cheap) fileserver and runs just the minimum installation. It 
boots from a
mostly full 500Mb hd and the idea was to use the rest for serving the 
other boxes.

I have lockups when updatedb is running using ide-2.4.19-p7.all.convert.10
driver. Controller is Ultra133-TX2 (PDC20269) and mobo is ASUS A7M266
(AMD761 northbridge).

Memory has been checked to be OK. (48 hours of memtest86 3.0)

Hi Jussi,
        I found out that the problem was not the Promise controller
but a bug in the ALI chipset. Disabling the specific driver for that
chipset (and DMA as well :/ ) gives me atleast the possibility to work.
The bug for the ALI was discussed in another thread.

What makes me worried now is that 2/3 people are reporting a similar
problem but using different chipsets. Can be a problem located somewhere
else???? Dunno..... just a guess.

In fact, I believe I found out that it's some weird driver interaction
problem.

I have an IDE controller on VIA 686B southbridge on motherboard and PDC20269
as a PCI card. Now, I had Linux on a drive attached to the VIA controller
without any problems. The drive became too small so I added the U133TX2 card
and a new drive and installed Linux on that one. No matter which one of the
installations is booted, the system will lock up if the VIA controller is in
use at the same time as the PDC. However, system seems to be stable (short
test priod though) if only the PDC controller is in use. (I left the old
drives attached to the VIA controller unmounted.)

Does this problem sound similar to yours?

seems similar to my problem. If I connect large (75-120G) disks on
both PDC channels and run /sbin/badblocks in parallel (dd might do, too)
I get a kernel panic/freeze. I get it even with no disk on the onboard
controller. I can reproduce this on two different VIA boards with both,
a PDC20267 and a PDC20262, too. On a board with Ali chiset, however
no error occured during a short (5 minutes) test. On a board with an
Intel
chipset I got some "DMA timeout" after 3 hours, but may be this was
an unrelated problem.
