I just tried this and it still panics at the same spot. I tried it with all four combinations of the two '#if 0' blocks in ata-disk.c. I'm going to play around with Mike's suggestion of instrumenting ad_interrupt with a bunch of debug prints and see if I can see what is happening. I'll do this right after I determine for sure that both the old and new driver are at least trying to read the same blocks from the disk for the disklabels. Sounds stupid I know, but I can cut the problem space in half if I can prove that they are least trying to go to the same spot on the disk. -steve To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-current" in the body of the message
