Same here. 11.04 on a ThinkPad T400. Behaves almost exactly like the kslowd issue from maverick. Only way I found to fix the problem in maverick was to freeze to the 2.6.32 kernel. Not an option for Natty.
Kernel hacker I am not, but happy to help however possible to sort this. Most annoying aspect is that it's inconsistent, but when activity spikes, it's definitely a kworker thread, 0:0 for me. Worst shortly after booting, after resuming from sleep, and when running from battery. Seems to be endemic among T400s. Did all my fellow T400 owners have the same issue with kslowd for 2.6.34 to 2.6.36?
