In my case (3.0-STABLE 2/8/1999) merely trying to write to a write-protected disk will cause a reboot. This is a _major_ problem, and is something that didn't exist about 1 month ago when I CVSupped another server. Anyone know what's causing these reboots? When mine reboots, I get: < messages about the disk being write protected > panic: dirty buffers Syncing disks... 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 ... When I tried it with Ctrl-C I got: < messages about the disk being write protected > panic: dirty buffers Syncing disks... 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 ...
