Subject: 2.6.20-git10: BUG at drivers/pci/pci.c:817 during suspend to disk

Hi,

I've got this in the resume-during-suspend phase of suspend to disk with
2.6.20-git10 on HPC nx6325:

PCI: Setting latency timer of device 0000:00:06.0 to 64
sata_sil 0000:00:12.0: resuming
BUG: at drivers/pci/pci.c:817 pcim_enable_device()

Call Trace:
 [<ffffffff8031c05e>] pcim_enable_device+0x93/0xb3
 [<ffffffff8039a74c>] ata_pci_device_do_resume+0x21/0x5e

 [<ffffffff8021555d>] sys_write+0x47/0x70
 [<ffffffff8025911e>] system_call+0x7e/0x83

The box has survived the entire suspend-resume cycle, though, and seems to be
fully functional.

Greetings,
Rafael
