This has nothing to do with the mount command; assigning to kernel
which kernel is this ?
I have the same problem. I have RedHat 7.2, kernel 2.4.9 (from the RPMs), two hard drives on ide0, an ASUS DVD on /deb/hdc. Every once in a while, the whole ide bus crashes, tries to reset (both IDE channels), then finally get the same thing as in the original post. Very disappointing :((
