Well the first thing I checked was vanilla 2.4.5, and I managed to bring that down hard too. It has nothing at all to do with reiserfs, but may be related to USB instead. I have been able to reproduce the problem by doing the following: a) Booting with X on vc/2 b) Logging into vc/6 instead c) Mounting a filesystem on my USB Zip drive d) Unmounting the filesystem again e) Unmounting the NFS mount f) Executing "rmmod -a" twice to clean out the now-unused modules (e.g. sd_mod, scsi_mod, usb-storage) g) Trying to switch back to vc/2 h) Oops! 2.4.4 seems OK; I guess I'll have to build those -pre kernels now.
