[Bug 658955] Re: Slow suspend to RAM with clocksource TSC on Maverick AMD64

[Angus Turnbull]

I've found a solution. The problem is that the clocksource TSC is
unstable (not just the AHCI driver). Adding:

clocksource=hpet

to the kernel boot command results in the first suspend working
properly.

** Summary changed:

- Slow suspend of AHCI driver on Lucid/Maverick AMD64
+ Slow suspend to RAM with clocksource TSC on Maverick AMD64

-- 
Slow suspend to RAM with clocksource TSC on Maverick AMD64
