I made a patch from the -current code for -stable and tried it. It fixed the data corruption (I was copying data between to 80Gb drives and I would be hard pressed to get 2 copies correct in a row). However the patch appears to make the machine rather unstable :( I can't get a crashdump since I stuffed up making the swap partition However since the machine appears to hang rather than crash I don't think that I would get a crashdump anyway. --- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
