To: stable@freebsd.org Date: Sat, 24 May 1997 13:01:06 +0100 (BST) Cc: Andrew Wilson X-Mailer: ELM [version 2.4 PL24 ME8a] Content-Type: text Sender: owner-stable@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Hi, I used cvsup to grab the latest 2.2-STABLE on Friday night, ran 'make world' and almost immediately began seeing problems reading my SCSI disk. The several errors on bootup report as: sd0(ncr0:0:0): MEDIUM ERROR info:62686 asc:11,0 Unrecovered read error, retries 3 While making a DAT backup of the disk 'cd /;tar cvfb /dev/rst0 20 .' The latest kernel reported: assertion "cp" failed: file = "../../pci/ncr.c" line 5542 sd0(ncr0:0:0) COMMAND FAILED (4 28) @f05ca200 And the x server died. A subsequent reboot reported no errors. The error seems to appear erratically. QUESTIONS: 1. is this problem a result of bad software in the kernel? 2. does this mean the NCR controller is toast? 3. does this mean the disk is trashed? 4. any recommendations?
