[.....] I spoke too soon. The increased DELAY allowed me to survive a make world, but some subsequent knews/leafnode/X activity hosed things again :-( The second time this happened, I did see a ata0: unwanted interrupt 1 status = 50 message on the console.... BTW, I'm running softupdates on a single monster partition: Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/wd0s1a 3671854 2912919 465187 86% / procfs 4 4 0 100% /proc kernfs 1 1 0 100% /kern but I don't think this is relevant (unless I'm experiencing more than one problem). -- Brian Don't _EVER_ lose your sense of humour !
