I've started having a problem with savecore on my laptop. I was doing some work on umass and managed to crash the machine. It goes down, kernel dumps to swap, reboots. Fine. On the way back up it tries to savecore and gets; ad0s2b: hard error reading fsbn 8661471 of 606584-606831 (ad0s2 bn 8661471; cn 539 tn 38 sn 42) ad0: DMA problem fallback to PIO mode ad0s2b: hard error reading fsbn 8661615 of 606584-606831 (ad0s2 bn 8661615; cn 539 tn 40 sn 60) status=59 error=40 ad0s2b: hard error reading fsbn 8661615 of 606584-606831 (ad0s2 bn 8661615; cn 539 tn 40 sn 60) status=59 error=40 [etc] This was with FreeBSD 4.5-PRERELEASE #9: Mon Dec 31 00:36:29 EST 2001 I assumed I had a bad disk, so replaced it. After replacement I got a crashdump for a different reason (apparently if you have if_foo.kld that requires miibus and loads it in loader.conf and miibus compiled into the kernel the first reference - like ifconfig - to it will crash the machine) and got similar messages on the second crash (not the first); ad0s2b: hard error reading fsbn 9390379 of 100976-101223 (ad0s2 bn 9390379; cn 584 tn 133 sn 40) ad0: DMA problem fallback to PIO mode ad0: DMA problem fallback to PIO mode ad0: DMA problem fallback to PIO mode [...] ad0: DMA problem fallback to PIO mode ad0s2b: hard error reading fsbn 9390619 of 100976-101223 (ad0s2 bn 9390619; cn 584 tn 137 sn 28) status=59 error=01 ad0: DMA problem fallback to PIO mode FreeBSD 4.5-RC #3: Wed Jan 23 11:54:19 EST 2002 The different locations are because I laid out the new disk somewhat differently. So now I'm somewhat confused. Hard errors following the installation, not the disk ? Anyone got suggestions ?
