It's probably time for a complete rebuild here. >Description: When unmounting an msdos filesystem, the system will reset exactly as if the reset button had been pressed. No core-dumps or panics are produced. I'm using an msdos lkm, but I have also noticed the problem when msdos-fs was compiled into the kernel. I have taken care to ensure the lkm is compiled in step with the kernel. >How-To-Repeat: mount an msdos filesystem. work on it for a while. unmount it, and FOOF! system blown away. Doesn't always happen. Running chkdsk under msdos show no evidence, before or afterwards, of any filesystem corruption MSDOS version is 4.01 >Fix: Fixed by Martin Renters - first flush dirty blocks. >Release-Note: >Audit-Trail: State-Changed-From-To: open->closed State-Changed-By: jkh State-Changed-When: Tue Oct 25 21:47:44 PDT 1994 State-Changed-Why: Martin Renters fixed the bug. >Unformatted:
