Hi,

the number of cylinders for one hd changed after I booted a kernel with ACPI support.

I got a new motherboard and had a problem with a normal kernel when i did a
shutdown -p, which caused a kernel panic after the sync step, so I tried
to use a ACPI kernel and thats where my problem with the hd started.

This is a part of the dmesg output for a non ACPI kernel of the new mb and
the disk. There is only one disk connected:

viaide0 at pci0 dev 8 function 0
viaide0: NVIDIA nForce3 250 IDE Controller (rev. 0xa2)
viaide0: bus-master DMA support present
viaide0: primary channel configured to compatibility mode
viaide0: primary channel interrupting at irq 14
atabus0 at viaide0 channel 0
viaide0: secondary channel configured to compatibility mode
viaide0: secondary channel interrupting at irq 15
[..]
wd0 at atabus0 drive 0: <WDC WD2500JB-00GVA0>
wd0: drive supports 16-sector PIO transfers, LBA48 addressing
wd0: 232 GB, 484521 cyl, 16 head, 63 sec, 512 bytes/sect x 488397168 sectors
wd0: 32-bit data port
wd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 5 (Ultra/100)
wd0(viaide0:0:0): using PIO mode 4, Ultra-DMA mode 5 (Ultra/100) (using DMA)

And here is the same part after i booted with the new ACPI kernel:

viaide0 at pci0 dev 8 function 0
viaide0: NVIDIA nForce3 250 IDE Controller (rev. 0xa2)
viaide0: bus-master DMA support present
viaide0: primary channel configured to compatibility mode
viaide0: primary channel interrupting at ioapic0 pin 14 (irq 14)
atabus0 at viaide0 channel 0
viaide0: secondary channel configured to compatibility mode
viaide0: secondary channel interrupting at ioapic0 pin 15 (irq 15)
[..]
wd0 at atabus0 drive 0: <WDC WD2500JB-00GVA0>
wd0: drive supports 16-sector PIO transfers, LBA48 addressing
wd0: 232 GB, 484518 cyl, 16 head, 63 sec, 512 bytes/sect x 488395055 sectors
wd0: 32-bit data port
wd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 5 (Ultra/100)
wd0(viaide0:0:0): using PIO mode 4, Ultra-DMA mode 5 (Ultra/100) (using DMA)

As you can see, the number of cylinders changed from 484521 to 484518 and
the following errors occurred, because the rc script tried to mount a
partition which was at the end of this disk:

wd0i: error reading fsbn 20971436 of 20971436-20971439 (wd0 bn 488396156; cn 484519 tn 15 sn 59), retrying
wd0: (id not found)
[same error repeated 6 times]

The number of sectors before I booted with the ACPI kernel matches the
manufactor spec: http://www.wdc.com/en/products/Products.asp?DriveID=42

I reduced the total size in the disklabel, changed the parition, did a newfs
and everything is working again.
Except that I lost my data on that partition and 3 cylinders.

How can a ACPI kernel change the number of cylinders for a disk?
I tried to boot with the old kernel and even switching back to the old mb, but
nothing gave the 3 cyl back.

Attached is the full dmesg of the acpi kernel and the old fdisk.wd0 before
I booted the ACPI kernel.

Bernd
