2.5.15 IDE possibly trying to scribble beyond end of device

Hi,

Just rebooted to 2.5.15 to find 'depmod -a' report I/O errors
on one of the files in the module tree.

Back in 2.4, trying to access the file (on my reiserfs root) reports:

May 10 12:56:26 nibbler kernel: attempt to access beyond end of device
May 10 12:56:26 nibbler kernel: 03:03: rw=0, want=807359916, limit=8185117

Everything else looks intact.

Running reiserfsck on the fs exits on an assertion error. Looks like I'll
have to re-mkfs the whole thing -- getting rid of the corrupt file seems
impossible.

The setup is:
K7/1GHz
VP_IDE: VIA vt82c686b (rev 40) IDE UDMA100 controller on pci00:07.1
hda: 156301488 sectors (80026 MB) w/2048KiB Cache, CHS=9729/255/63, UDMA(100)
/dev/hda:
multcount = 0 (off)
I/O support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 9729/255/63, sectors = 156301488, start = 0
DMA modes: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 *udma5

I haven't observed similar problems in any of 2.5.14, 2.5.14-dj[12].
