tests with IDE controller ... IRQ xy: nobody cared!

Hi PA,

It has been quite a long time since I last tried to get PCI IDE controllers working in my C3k. So I decided whether anything has change in this situation lately
(Debian/testing, 2.6.11-rc3-pa3, 32bit, gcc-3.4.4).

I tried a noname Silicon Image Sil680 based IDE controller and a Promise Ultra100 Tx2 (I compiled all IDE stuff and IDE drivers as modules, so I could more easily test it). I didn't have any luck getting the IDE controller to work, but at least now I got much different error messages than I used to get (months ago).
Maybe this might help you to locate the problem:

kernel: Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
kernel: ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx

This particular message showed up when I tried the Promise card with the pdc202xx_new driver in a 33MHz slot. Exactly the same backtrace occurs when I put the card in a 66MHz slot and also when I tried the Silicon Image card with the siimage driver (33MHz).

As you can see from the log, the hdd and the DVD burner are correctly detected, but I cannot access them; a 'mount /dev/hda ...' or a 'cat /dev/hda' results in 'cannot open /dev/hda'.

(The Promise card with the pdc202xx_old driver does load, but
doesn't detect anything nor does anything show up in the logs)

Thanks a lot in advance,
Max

Hello Max,

Sorry if I have no idea for your pb but more an advise to request:

...

For the deployement of a custom hpux 11.11 we foreseen to build an ignite=

image on a dvd (not sure that could stil stand on a cd as for previous 11= .00).

The question is: what unix tool(s) would you advise me to burn those dvd (hpux or linux)?

Thanks in advance,
Joel

For linux there are basically three backends:

1. cdrecord-ProDVD / cdrtools
(non-GPL, ftp://ftp.berlios.de/pub/cdrecord/ProDVD/ precompiled binaries available for non-commercial use)

2. cdrecord + DVD-patch
(GPL, http://people.mandrakesoft.com/~warly/files/cdrtools)

3. dvd+-rw-tools / growisofs
(GPL, http://fy.chalmers.se/~appro/linux/DVD+RW/)

As for GUIs/frontends, the most popular ones are
- k3b (recommended, www.k3b.org)
- xcdroast (www.xcdroast.org)
- nautilus-cd-burner
I can also recommend
- webCDwriter Pro (non-free: http://joerghaeger.de/webCDwriter/pro.html).
if you share DVD writer in your office with other people.

Most of these frontends use/support the dvd+rw-tools package.

Note that UDF (the 'standard' filesystem for DVDs) is still not very well supported under linux, so most DVD burn apps use the iso9660 filesystem instead (but that should not matter, unless you want to burn movie-DVDs).

Greetings,
Max
