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:

  #0  add_to_page_cache_unique (page=0x81042840, mapping=0x810b7520, offset=0, hash=0x8109df5c)
