It doesn't matter whether I read any data from it or not before the umount command. Subsequent attempts to access the drive in any way -- mount, dd, etc. -- hang and the processes can't be killed, even with kill -9. I have to reboot to get out of it. The rest of the system continues to work normally, except that within a few minutes, I start getting temporary hangs (about 5 seconds duration) every couple of minutes. The keyboard locks, the screen freezes, then a few seconds later everything unfreezes and it works OK for another few minutes. Playing an audio CD doesn't trigger this problem; only mounting and unmounting does. Since I haven't been using my CD drive much lately, I'm not certain exactly when this problem started. It happens under both the "original" 2.4.0-prerelease and one patched with the latest prerelease-diff. I'm pretty certain it didn't happen under 2.4.0-test12, but I can't remember if I used the CD under any of the test13-pre versions or not. My system is pretty much standard Slackware 7.1, except for the 2.4.0 kernel and upgrades to modutils, binutils, etc. to bring everything into sync with what's specified in Documentation/Changes. The compiler is egcs-2.91.66.
