SubjectIDE + OOPS 2.4.14


linux single hdb=16383,16,63 hdb=noprobe

causes attached oops. I suspect that the 16383 number overflows something,
as attached oops makes no sense to me.

If I swap the hdb=16xxx and hdb=noprobe arguments, no OOPS occurs.

IDE info :

PIIX4: IDE controller on PCI bus 00 dev f9
PIIX4: chipset revision 2
PIIX4: not 100% native mode: will probe irqs later

hdd: ATAPI 40X DVD-ROM drive, 512kB Cache, UDMA(33)

the /dev/hdb info is totally wrong, it is a 61 GB disk, not 32 GB.
Correct info :

[root@wrkst igmar]# ./setmax /dev/hdb
Using device /dev/hdb
native max address: 120064895
that is 61473226752 bytes, 61.5 GB
lba capacity: 66055248 sectors (33820286976 bytes)

Anyone got a solution for the above problem ??
