I know that I am the one doing the bad things but I've crashed my computer a half dozen times doing this and it would be nice if someone could look into this. I think that the kernel something in the kernel is getting fouled up.
Background: ----------- I have a digital camera that uses flash memory cards that fit into an adapter that goes into the pcmcia slot on my laptop. The cards pretend to be little vfat formatted disks.
Steps to reproduce: ------------------- 1) insert card 2) mount card "mount -t vfat /dev/hdc1 /mnt/pccard" 3) cd /mnt/pccard 4) eject card 5) Re-insert card 6) mount card again First the mount process hangs and the computer becomes rather unresponsive. The mouse freezes for a few seconds then catches up. However, the computer seems to be unstable and eventually hangs completely. Sort of like the way that Windows does if you keep going after a GPF.
Note: ----- Everything is OK as long as I don't happen to have a shell in a directory that is on the pcmcia device. The pcmcia services seem to do the right thing and unmount the file system and then free up the device.
I bet the problem is that the kernel or the PCMCIA services don't know how to deal with the fact that the umount fails because the file system is buxy.
