Title:
  hdparm and ata_id makes USB drive hang

Status in Linux:
  Invalid
Status in hdparm package in Ubuntu:
  Invalid
Status in linux package in Ubuntu:
  Won't Fix

Bug description:
  I have installed Karmic on a USB drive. Because of bug #419231 I need
  to add ums_cypress to the initrd for this. During boot I noticed
  several long waits with no activity. Bootchart indicated it was hdparm
  hanging. When I run hdparm manually it hangs for 15 seconds:

  $ time sudo hdparm /dev/sdb

  /dev/sdb:
   HDIO_DRIVE_CMD(identify) failed: Invalid exchange
   readonly      =  0 (off)
   readahead     = 256 (on)
   geometry      = 30401/255/63, sectors = 488397168, start = 0

  real	0m15.979s
  user	0m0.000s
  sys	0m0.008s

  It leaves this in dmesg:

  Interesting enough the time stamps all end with the same millisecond
  part, like in bug #397096.
