Public bug reported:
Both Lucid and Maverick kernels suspend to RAM very slowly (5 minute
delay) on the first suspend after a cold boot. It appears that the
kernel is hanging for that time on suspending the AHCI device, per the
DMESG logfile included. I first noticed the problem halfway through the
updates for the 6 months I ran Lucid, and it's still present in Maverick
release (Karmic seemed to be OK). Interestingly under Lucid at least the
first suspend showed the delay, and subsequent suspends did not.
I have a 1Tb Western Digital Green HDD installed and a SH-S223F DVDRW
drive, both running under AHCI with no ATA devices configured in the
BIOS. After suspend the system often comes up normally in several
seconds; sometimes it doesn't resume, showing disk access errors and
requiring a hard reset.
