I've got a mipsel linux 2.4.18 system that has a compact flash IDE
disk as hda. For some reason, in grok_partitions, the kernel goes
bye-bye. I've traced it as far as read_page_cache().
The console prints this:
ide0 at 0x2200-0x2207,0x220a on irq 3
config_drive_xfer_rate for drive hda (0)
hda: 250880 sectors (128 MB) w/1KiB Cache, CHS=980/8/32, DMA
Partition check:
/dev/ide/host0/bus0/target0/lun0:
Then hangs. If I use KGDB to trace the kernel to that point, and do a
backtrace, here's what I see:

Any suggestions?
