I think I know what the problem is.

In include/linux/libata.h, make sure the preprocessor declarations are as follows. I think the defaults have ATA_ENABLE_PATA undefined.

#define ATA_ENABLE_ATAPI /* undefine to disable ATAPI support */
#define ATA_ENABLE_PATA /* define to enable PATA support in some
* low-level drivers */


Thanks, now it loads correctly. Unfortunately the clock drift still occurs
with pata_pdc2027x. I'm guessing here, but can clock drift have anything
to do with IRQs? Also, is it normal to see errors in /proc/interrupt?

Are you by chance running ntpd? And have you checked to see if it dies as soon as it starts? There's a bug in the ntp M/L wrt execstack.
