The gory details are at <http://bugzilla.kernel.org/show_bug.cgi?id=5989>, but the short summary:
With 2.6.15, S3 sleep and wake were 98% fine (once in a while waking would hang, but I haven't managed to reproduce it). However, with 2.6.16-rc1 with the acpi-20060113 patch, the first sleep and wake goes fine and the second sleep hangs at the 'Stopping tasks'.
With tons of debugging turned on, the second sleep does not hang, but the wakeup hangs. With 0x1F as the acpi debug_level, the second sleep still hangs and produces some output across a serial console. In the second sleep (after the second 'Stopping tasks'), it endlessly repeats a short sequence of
exregion-0182 ... exregion-0287 ... exregion-0182 ...
The machine is a TP 600X with the latest (1.11) BIOS and a fixed DSDT so that it can S3 sleep at all.
