Kernel 2.6.30 and CDROM/PATA? [Solved]

I've upgraded to 2.6.30, which broke the entire sound system: I've managed
to fix most of it, but the system now locks solid with a kernel oops 0000 when
I load an audio or data CDROM (Null pointer dereference at 00000024). I
suspect the problem is actuall with the PATA interface - the main HD is SATA,
but the CDROM is on a (standard Intel onboard) PATA bus.

Everything worked in 2.6.28 (well, everything that usually works) and I've double-
checked the configuration changes; has anyone seen any similar problem?

Thanks - Will

cwr,

Do you use both the old IDE and SATA kernel branches or have you migrated to the PATA drivers under libata?

The PATA driver in libata works for my AMD/nvidia PATA chip set. The device appears as /dev/sr0

After upgrading from 2.6.28 to 2.6.29-r2 then r3 which broke X and sound. Now that things have settled, yesterday, my /dev/ pointers had changed to cdrom1 and so forth. Did yours ?

2.6.30 with libata (pata_via) works well for me (VIA IDE interface).

I had a couple of the CMD640 chipset flags set, since it's used on another machine.
They haven't been a problem before, but apparently they are now; I turned them
off, and the CDROM worked.

Thanks for the ideas - Will
