A few months ago i was getting locked up by NFS bugs, to try to track down the problem i enabled crashdumps and the next time it locked up i broke to DDB and asked for a crashdump. When it then rebooted entire partitions were destroyed on the same disk that the dump device was configured. I was told that when the dump routine is called it's not aware of LBA mode being in flags and turns off the translation, this tended to make the dump get stuffed in the wrong spot on my disk. In fact i've been afraid to take a crashdump since on all my IDE boxes. This used to work fine for me, I've diabled LBA in flags, but still haven't had the corage to take a crashdump on the IDE boxen. Several people on -hackers or perhaps -current told me this. I'll find the messages if you want them. -Alfred To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
