This means that the ide driver does see the parameter. But it doesn't
want to apply it. Here is a piece of code that applies the parameter in
the kernel:
block =
rq->sector;
if (blk_fs_request(rq)
&&
(drive->media == ide_disk || drive->media == ide_floppy))
{
block +=
drive->sect0;
}
/* Yecch - this will shift the entire
interval,
possibly killing some innocent following sector
*/
if (block == 0 && drive->remap_0_to_1 ==
1)
block = 1; /* redirect MBR access to EZ-Drive partn
table */
I.e., this can fail only if blk_fs_request(rq) is false (which cannot
happen, afaik) or if the media is misdetected. Could you please post the
output of the following command?
cat /proc/ide/hda/media
Does booting with any of the following lines work around the bug?
linux load=ide-generic hda=16383,255,63 hda=remap63
linux load=ide-disk,ide-generic hda=remap63
Does booting with the following line result in a completely invalid
partition table (i.e.: I want to see whether the code above is executed
at all)?
linux load=ide-generic hda=remap hda=remap63
