Hi, just for info, I seemingly had the same error occurring yesterday, but I also failed to retrieve information from the debugfs. Also on 2.6.38.2, chipset being H55 Express. Seems to happen after a long uptime. I will be more careful to retrieve debug information next time.
Another sort-of-regression I noticed since moving to 2.6.38 is the 30 second waiting period when resuming. However, I have no idea what driver might be the cause.
