Hi Jeff,

I have a Intel ICH6M chipset and am using ata_piix as my
default disk driver. With the SUSE patched 2.6.11.4 kernel
(it has some libata patches) my DVD-RAM drive works, with
2.6.13-rc3 it doesn't work. My .config is nearly identical
for both kernels (except options introduced after 2.6.11).

I have two suspects: the changed interrupt routing and
libata version differences. Especially strange is the fact
that both kernels seem to disagree with lspci about the
interrupts assigned to the SATA controller.

Please find dmesg, /proc/interrupts and lspci -v attached
for both kernels.

Regards,
Carl-Daniel
