I can confirm the same oops on 2.6.20-ck1 with pktcdvd either as module or as built-in. I can assume perhaps this is not so much an issue with the pktcdvd driver as it is with the libata drivers and scsi. Beats me, I'll leave it up to you. - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
