           Summary: irq 10: nobody cared!
    Kernel Version: 2.6.10-rc4
            Status: NEW
          Severity: normal
             Owner: bzolnier at elka.pw.edu.pl
         Submitter: rbrito at users.sf.net


Distribution: Debian testing
Hardware Environment: Asus A7V board with VIA KT133 chipset and Promise PDC20265
controller.
Software Environment: GCC 3.3.5 and everything else from Debian testing.
Problem Description:

The situation is this: I have an Asus A7V motherboard with 2 VIA
vt82c686a controllers and 2 Promise PDC20265 controllers.

I recently bought myself a new DVD recorder and since Alan Cox told
me[*] that the Promise controllers had problems with ATAPI devices, I
decided to arrange my system this way:

/dev/hda: the DVD recorder (VIA controller, master)
/dev/hdc: an old CD recorder (VIA controller, master)
/dev/hde: my first HD (Promise controller, master)
/dev/hdg: my second HD (Promise controller, master)

The Promise controller is able to control the HDs (which now have
exclusive 80-pin cables) at their maximum, but I get the following
stack trace if I have /dev/hdg turned on:

- - - - - - - - - - - - - - - - - - - - - - -  - - - - - - - - - - - -

This is just an excerpt of the messages. I can provide much more
details if I know what is relevant.

I had already posted some old dmesg logs at my site
<http://www.ime.usp.br/~rbrito/ide-problem/>, but this was before I
got myself a second 80-ribbon cable (I expected that the problem would
go away, but it didn't).

Any other comments are more than welcome.


Thanks in advance, Rogério Brito.

Steps to reproduce:
Just booting the system as mentioned above makes the system dump a stack trace.
