[Bug 810191] [NEW] Hibernate produces errors, may hang

[Hendrik]

Public bug reported:

Ubuntu 11.04 (32 bit) on a HP EliteBook 6930p.

Hibernate (suspend-to-disk) produces the errors below (sometimes
multiple times) and occasionally completely hangs the system - in which
case it has to be powered off, losing all session data.

[16239.822402] ACPI: Error updating fan power state
[16239.822408] legacy_resume(): acpi_device_resume+0x0/0x27 returns -19
[16239.822410] PM: Device PNP0C0B:00 failed to restore: error -19

** Affects: acpid (Ubuntu)
     Importance: Undecided
         Status: New
