Ok, I got a hold of a 160GB Samsung SP1604N, and was able to try out
lba48 with 2.2+ide backport myself.
So, I took Marc-Christian Petersen's 2.2.25-secure patchset
(sourceforge.net/projects/wolk) that includes Krzysztof Olędzki's ide
2.2.21-06162002 patch and booted. After some severe confusion, it turned out
2.2 + the ide backport supports >137GB disk just fine.
The confusion arose from that I had used an old version of fdisk (v2.10f
from redhat-6.2) to create a partition to hda. fdisk probably read the disk
geometry all wrong and created too big partition. And the kernel seems to
have believed the bogus partition table. When I tried mkfs.ext2 /dev/hda1,
it ran well until about 1193 inode groups (little over 41.9% of total), and
then the kernel begun spitting out SectorIdNotFound IDE errors (see the log
below). After I found out that mkfs on 2.4.20 kernel did the same, I begun
suspecting 2.2 ide was not to blame. I found out that badblocks -w /dev/hda
ran all ok up to 160GB on both 2.2 and 2.4. And when I did mkfs.ext2 on
/dev/hda (omitting the partition table altogether), 2.2 worked all solid. I
tried filling up the file system, and there were no problems. I also did
some other short stress tests and everything seems to work based on this
quick test.
I also tried creating the partition with cfdisk, and it seemed to handle the
larger disk right (see the attached log). The mkfs.ext2 succeeded and I was
able to mount and use the partition.
The hardware is Abit ST6R, I tried both i815 IDE (PIIX4 chipset revision 17)
and HPT370A IDE (HPT370A chipset revision 4). FWIW, both gave >42MB/s with
hdparm -t. (Both were reportedly using UDMA mode5.)
Thanks to Andre Hedrick, Krzysztof Olędzki, Marc-Christian Petersen and all
involved in the linux ide development!
