SubjectRe: IDE Driver Reports Erroneous Errors While Mounting NWFS 2.0 at boot


Perhaps I am not understanding what the error is reporting. The range
error states that I am asking for 1715620. Is this number a 1024 byte
block address or the LBA offset of the disk and not an LBA sector
offset? NetWare does everything as LBA based, so we call
set_blocksize(dev, 512) and set the devices to a 512 sector block size.
What could conceivable be going on here is that for some reason, the
driver is not in a state where we can do this, and we are breaking it,
then running off the end of the disk.

The device is 850/64/63 so it's sectors are 0x3451E0, but the driver is
reporting we are off the end at 0x1A2762, which is bogus, if the device
is reporting LBA ranges.

Perhaps this sheds some light. What do you think?
