$ fdisk -l /dev/sda

Disk /dev/sda: 1 heads, 35843670 sectors, 1 cylinders
Units = cylinders of 35843670 * 512 bytes

Device Boot Start End Blocks Id System
/dev/sda1 * 1 1 32098+ 83 Linux
Partition 1 has different physical/logical beginnings (non-Linux?):
phys=(0, 1, 1) logical=(0, 0, 64)
Partition 1 has different physical/logical endings:
phys=(3, 254, 63) logical=(0, 0, 64260)
Partition 1 does not end on cylinder boundary:
phys=(3, 254, 63) should be (3, 0, 35843670)
/dev/sda2 1 1 168682+ 83 Linux
Partition 2 has different physical/logical beginnings (non-Linux?):
phys=(4, 0, 1) logical=(0, 0, 64261)
Partition 2 has different physical/logical endings:
phys=(24, 254, 63) logical=(0, 0, 401625)
Partition 2 does not end on cylinder boundary:
phys=(24, 254, 63) should be (24, 0, 35843670)
....

One head, one cylinder and lots of sectors??
I put some debug in drivers/scsi/scsicam.c and it doesn't
seem like it was called.

Is my fdisk (from RH 7.2) too old?

No please: Just please don't look at ide-scsi in 2.5.21
without applying IDE patch number 86.

$ cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: SEAGATE Model: ST318451LW Rev: 0003
Type: Direct-Access ANSI SCSI revision: 03

This disk i(/dev/sda) is an Ultra 160 (SPI) connected to
a Tekram DC-309U3W controller.

The reported problem occurs with all disks seen by the scsi
subsystem in lk 2.5.21 that I have tested including usb mass
storage and ieee1394 sbp2. I am not aware of any ATA disks
that support ATAPI and hence could be used with ide-scsi
driver (if it didn't crash in 2.5.21).

My guess is that there is a problem in the block (or genhd)
subsystem.

No, it is too modified.
Get a vanilla fdisk from a recent util-linux,
and probably all will be fine.

Andries,
Thanks. Confirming that the fdisk in util-linux-2.11r
works fine.
