Has anyone experienced any kernel related bug(s) in 4.0.1 that may affect dump & dd ? It seems that they always got into a disk-wait state whenever I do a large dump onto a scsi tape or whenever I need to do a remote extract from a dataless client (during a remote install). This is very annoying. This happens on my Sun-4/280S-24 under 4.0.1. The whole net is running 4.0.1 and it seems that this doesn't happen under 4.0 (so much for the upgrade then). I didn't do anything fancy though -- I just extracted the 4.0.1 upgrade tape while I'm still at 4.0, then select all the options, and then rebuild the kernel (discarding unneeded options from my kernel config files of course). I don't have any fancy hardware on my 4/280S either -- just a plain old 4/280S-8 plus an extra 16 meg of Clearpoint memory, a 1/4-inch scsi cartridage tape drive from Sun, a 380meg Fuji Eagle and a 892meg Hitachi hooking off a Xylogics 451 (all three from Sun). The only other SunOS patch I did applied is the ufs patch that is supposed to cure the 'itrunc' barfs that I get from time to time whenever the filesystem is busy. I didn't get this sort of thing before when I was using 4.0 (generic kernel) though. Can someone enlighten me as to what have I done wrong or may have missed ?
