Hi,

I have a large number of IDE hard disks here where I work.  Since moving to
2.4.19 from 2.4.17, several of these disks have stopped working, resulting
in a kernel panic after the drive has declared itself to have 0 cylinders!
All the disks that have broken are the following:

Seagate 80GB U6 ST380020ACE with Firmware version 4.65

We have lots of these same drives, with FW v 3.34, that all work fine.  I do
not have a single drive with the 4.65 firmware working.  

My problem is that these drives used to work fine, with 2.4.17.  They are
not obsolete hardware, I think they are all less than 6 months old.

I have seen this on CS5530 with the standard kernel PCI IDE, and on SIS630
with the SIS Kernel IDE driver.  

Setting ide=nodma makes no difference.

Here is an excerpt from the kernel console booting:


....
hda: ST380020ACE, ATA DISK drive
....
hda: task_no_data_intr: status=0x51 { DriveReady SeekComplete Error }
hda: task_no_data_intr: error=0x04  { DriveStatusError }
hda: setmax_ext LBA 1, native 0
hda: 0 sectors (0 MB) w/2048KiB Cache, CHS 0/255/63, (U)DMA
....
hda2: bad access: block=2, count=2
end_request: I/O error, dev 03:02 (hda), sector 2
EXT3-fs: unable to read superblock
hda2: bad access: block=2, count=2
end_request: I/O error, dev 03:02 (hda), sector 2
EXT3-fs: unable to read superblock
Kernel panic: VFS: Unable to mount root fs on 03:02


Is this a result of all the new IDE stuff that went in in 2.4.19???

Cheers for any help,
