Owens" To: questions list FreeBSD Subject: CDRom w/NFS access (?) crashes system Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: questions-owner@freebsd.org Precedence: bulk Howdy, I have yet another problem. :-) Sorry to dump on this list, but I'm trying to pull off quite a bit with our beloved OS... Anyway, one of my systems looks like this: P/90 CPU, 32 megs RAM. 2.0.5-RELEASE FBSD NCR 83c825 SCSI PCI controller COMPEX ENET-32 PCI ethernet (DEC chipset) ISA SVGA card (ATI, yuck, soon to replace) 1 gig Conner SCSI-2 drive NEC 4x SCSI CDROM drive SoundBlaster 16 (adaptec SCSI controller set to IRQ 9 - not used) Ok... I was running Xwindows and had lots of xterms open and telnet sessions to various places. "Top" claimed that swap was around 12%. Both the hard drive and the CDROM are on the NCR controller. Periodicly, espcially (it seems) when I use the cdrom, I see these messages: /kernel: ncr0 targ 6?: ERROR (81:40) (8-28-0) (8/13) @ (1008:0). /kernel: reg: da 10 c0 13 47 8 6 f 1 8 6 28 80 0 8 0. /kernel: ncr0: restart (fatal error). /kernel: sd0(ncr0:6:0): COMMAND FAILED (9 ff) @f09a3e00. /kernel: sd0(ncr0:6:0): COMMAND FAILED (9 ff) @f08b5400. /kernel: cd0(ncr0:2:0): COMMAND FAILED (9 ff) @f08b5a00. /kernel: ncr0: timeout ccb=f08b5a00 (skip) /kernel: ncr0: reset by timeout. /kernel: sd0(ncr0:6:0): FAST SCSI-2 100ns (10 Mb/sec) offset 8. /kernel: sd0(ncr0:6:0): UNIT ATTENTION asc:29,0 sd0(ncr0:6:0): Power on, reset, or bus device reset occurred field replaceable unit: 14 /kernel: , retries:3 This didn't make me too happy, but everything seemed to work OK, mostly. Today, I was running Xwindows and had lots of xterms open and telnet sessions to various places. "Top" claimed that swap was around 12%. I mounted a cd and exported the mountpoint via NFS. Several other systems NFS-mounted the cdrom and started chewing away at it. (DOS-boxes installing windows off of the CDROM, actually :-). All seemed well. I even noted, impressed, that top showed that the nfsiod processes where using virtually NO cpu time! And then, with no warning, my machine resets! No panic messages or anything. Just a blank screen with warm fuzzy BIOS messages appearing. :-( Anyhow, I feel quite sure that not everything is as it should be and was wondering if any of you brave chaps had anything to say about my tale. thanks, --- ------------------------------------------------------------------------- Charles Owens Email: owensc@enc.edu "I read somewhere to learn is to Information Technology Services remember... and I've learned that Eastern Nazarene College we've all forgot..." - King's X -------------------------------------------------------------------------
