Comment 1 Luming Yu 2004-12-23 00:55:35 UTC 
Since 2.6.7, the Changes for drivers/pci/pci-driver.c@1.37 make my
ASUS 2400NE hang on S1 resume. 

S1 works well after reverting that patch.

Should we by-pass pci_default_suspend(resume) for S1?
Because, ACPI spec defines : in S1, all system context is preserved 
with the exception of CPU caches.
