Title:
  Random SATA drives on PMPs on sata_sil24 cards not being detected at
  boot

Status in The Linux Kernel:
  Confirmed
Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I just updated my box from Oneiric to Precise (linux-
  generic-3.2.0.23.25).

  The box has 22 SATA drives,
  6 on ICH10R
  15 on three sata_sil24 PCIe 1-port cards using three 1:5 PMPs
  1 on a sata_sil PCI32 4-port card

  After upgrading, two things are apparent:
  1) GRUB hangs for quite a long time upon booting, but eventually continues. dmesg (attached) mentions a whole lot of hard resetting of my sata_sil24 devices until finally continuing.
  2) Random SATA drives attached to the sata_sil24 will be missing.

  dmesg attached, other output to follow.

  WORKAROUND: Hot-unplugging and re-plugging the affected drives
  properly presents them to the system, and I can then use them.
