[Bug 301353] Re: HP Pavilion dv5: ATA exception on resume from suspend

[Paul Swanson]

** Description changed:

  On resume from suspend in Ubuntu 8.10 (Intrepid Ibex) the ATA driver
  throws a series of exceptions, as a result the filesystems can not be
  accessed and the computer needs to be rebooted. Hibernate, however, does
  work and does not have this problem, suspend / resume only. The linux
  kernel version is the latest 2.6.27-7.
- 
- On the NB Win-Vista + Ubunto 8.10 +9.4. Problem happens especially after
- closing NB-Lid with eithet Ubuntu running -- with Vista no proble.
  
  The initial error message on resume is:
  
  btusb_intr_complete: hci0 urb f7d94a00 failed to resubmit (2)
  ata2: exception Emask 0x10 SAct 0x0 SErr 0x0 action 0x9 t4
  ata2: irq_stat 0x00000040, connection status changed
  ata1: exception Emask 0x10 SAct 0x0 SErr 0x0 action 0x9 t4
  ata1: irq_stat 0x00000040, connection status changed
  sd 0:0:0:0: rejecting I/O to offline device
  PM: Device 0:0:0:0; failed to resume: error 65536
  
  Then, as nothing is able function properly, the most repeated error
  message is as follows:
  
  ata1: exception Emask 0x10 SAct 0x0 SErr 0x4000000 action 0xe frozen
  ata1: SError: { DevExch }
  ata2: exception Emask 0x10 SAct 0x0 SErr 0x4000000 action 0xe frozen
  ata2: irq_stat 0x00000040, connection status changed
  ata2: SError: { DevExch }
  
  There are a variety of other error messages thrown about ext3 file
  systems not being to be re-mounted, but I haven't been able to capture
  those yet.
  
  I'm running a fresh copy of Ubuntu 8.10 (Intrepid Ibex), with the latest
  updates, on a reasonably new HP Pavilion dv5 (1075er) notebook.
  
  Rationale:
  
  Originally I posted my problem under bug #158050 but later I realised
  that this was for an older kernel version. Then I thought that bug
  #273323 would be a better fit, but that has since digressed into a KDE
  discussion, entirely irrelevant to my problem. I've looked at every
  Intrepid suspend / resume bug listed and none are specific to my
  distribution version, kernel version or hardware so I'm starting a new
  one.
