I updated my 4.1-STABLE yesterday. Today I tried to read a CD-ROM (the FreeBSD 4.1-R install CD, and also one generic data CD I made a while back that was ok on this system before) and the mount never completes. Here's what happens. I insert the CD and type "mount /cdrom". The mount command returns. The /var/log/messages syslog contains this entry: /kernel: cd9660: RockRidge Extension I do an "ls /cdrom" and I get either -r-xr-xr-x 1 root wheel 0 Dec 31 1969 /cdrom* or some generic "input/output error" from ls. Before the mount, the /cdrom directory looks like this: drwxr-xr-x 2 khera wheel 512 Aug 11 14:13 /cdrom The syslog now contains this entry: /kernel: RRIP without PX field? I can no longer umount or "eject -f" the drive: umount: unmount of /cdrom failed: Invalid argument eject: Device busy However, after running eject, I can manually eject the disk. The "mount" command says this: /dev/acd0c on /cdrom (cd9660, local, nodev, nosuid, read-only, mounted by khera, reads: sync 3 async 0) It matters not whether I run mount as root or as a user. The only way out is a reboot. Booting the 4.1-R kernel.GENERIC, I can mount and read the CD-ROM just fine. It worked fine as of last friday as well, when I last did an update and used the CD-ROM. To me, this rules out hardware problems. I just cvsup'd again, and rebuilt a kernel (with DMA for ATAPI turned off) but that made no difference. (about 2:30pm EDT 23-AUG-2000) Any clues as to what to do to get back my CD-ROM drive functionality? Anyone else experiencing this trouble? Thanks.
