Title:
  Cannot suspend HP ProLiant SE316M1R2

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  pm-suspend does not work on HP ProLiant SE316M1R2 system.

  I am not sure if hardware actually supports that though, but there is
  kernel crash (see syslog.txt attached with Call Trace) which maybe is
  the cause.

  Monitor goes off for few seconds but after that system resumes and
  works as before.

  Also, some interesting lines:

  May  7 20:58:23 tomashp-server kernel: [ 4374.025981] pci_legacy_suspend(): hpsa_suspend+0x0/0x10 [hpsa] returns -38
  May  7 20:58:23 tomashp-server kernel: [ 4374.025986] dpm_run_callback(): pci_pm_freeze+0x0/0xe0 returns -38
  May  7 20:58:23 tomashp-server kernel: [ 4374.025987] PM: Device 0000:06:00.0 failed to freeze async: error -38s2disks

  These lines also appears when using s2disk.

  s2ram gives:

  KMS graphics driver is in use, skipping quirks.
  s2ram_do: Invalid argument
