More info: After rebooting, as root, I mounted the floppy again and started a recursive copy off it using: cd /a; tar cvf - . | (cd ~/mydir; tar --unlink -xpf - ) (in a script I use). It looked like it was going well, I got my prompt back, and did a "umount /a" (while the floppy light was still on fwiw). After a second or two, before the umount command came back, the machine froze again. A hard boot was req'd to get control of the machine.

I was able to ls the root directory. No | problems so far. | | Then in my shell I started typing a command to copy a file off | the floppy: | | cp -p /a/ | | At this point I hit Ctrl^D to get a directory listing of the | available matching files (bound to the tcsh | delete-char-or-list-or-eof function in tcsh, as is standard; type | "bindkeys" to check). | | The machine completely froze. The X mouse cursor was dead. | Ctrl-Alt-Backspace would not quit X. Ctrl-Alt-Del would not | reboot the machine. Attempts to switch VTYs were ignored. | No response for anything I tried. | | I hard-booted and (after much fsck'ing) checked the 3.4 errata.html | file on freebsd.org, and then sent this PR. | |>How-To-Repeat: | | Perform the above action and see if it happens for you. | | I'm hesitant to try tcsh matching files list on a floppy again | right now (I need to get a full backup made). | |>Fix: | | Unknown.
