Kernel panic while mounting a CD-ROM drive

Hello!
The same happens on my C3000 using the prebuild kernels from parisc-linux.org and
a IDE cdrom drive.
[but there is some progress as my USB keyboard works again so I can use the local monitor for login]. I think the last kernel I tested was version 2.6.12-rc5-pa3What 'worries' me is that I can see a message like 'module
ide_cdmissing' when booting.
Please capture and post the entire console output from firmware prompt until "login" prompt.

So far I don't know if that message indicates some error in the kernel (build) or if my configuration tells the kernel to load it 'dynamically' afterwards (found nothing in
/etc/...)
If the kernel boots at all, you can look in /lib/modules/uname -r/kernel/drivers/ide/

BTW: When I use a serial cable and connect it a PC running minicom I get normal console output, but suddenly (during hardware detection if
I remember right) it starts to beep a lot and I get only
garbage on the screen. After that 'dataquake' is over it works again ...
I expect this is because the suckyio chip gets reset by the pdc_io_reset_devices() call in sba_iommu.c. And since the serial device is integrated in suckyio, serial gets pounded as well.

When I have some time this weekend to test the newest kernel I will try to log the boot message and kernel panic again - the last time it was somehow missing from my minicom logfile ...)
that would be good.
thanks,
grant
