At least one other person has reported filesystem corruption due to kstack underflows which went away when I bumped UPAGES from 2 to 3. I don't think the stack fixes for the IDE drivers have been MFCd to -stable yet so heavy IDE use could be hitting up against the kstack problem. -Matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
