[plug] server failing with bizarre disk errors

[Craig Ringer]

Sorry for the replies-to-self...

Also tried disabling DMA, unmaskirq, 32bit IO, etc. Current drive params:


/dev/hda:
  multcount    =  0 (off)
  I/O support  =  0 (16-bit)
  unmaskirq    =  0 (off)
  using_dma    =  0 (off)
  keepsettings =  0 (off)
  nowerr       =  0 (off)
  readonly     =  0 (off)
  readahead    =  8 (on)
  geometry     = 232581/16/63, sectors = 234441648, start = 0
  busstate     =  1 (on)

  multcount    =  0 (off)
  I/O support  =  0 (16-bit)
  unmaskirq    =  0 (off)
  using_dma    =  0 (off)
  keepsettings =  0 (off)
  nowerr       =  0 (off)
  readonly     =  0 (off)
  readahead    =  8 (on)
  geometry     = 9729/255/63, sectors = 156301488, start = 0
  busstate     =  1 (on)
