ksoftirqd causes massive disk access

User-Agent: Mozilla/5.0 (compatible; Konqueror/3.5; Linux) KHTML/3.5.10 (like Gecko) SUSE The ksoftirqd problem has emerged again. Resolution by letting lay things far off has not worked. However now it has emerged in a somehow different flavour causing massive disk acccess instead of 100% cpu load. see for the old os11.1-related bug: Bug 465039. Rebooting is the only choice. It is not possible to work seriously with a system like this! Reproducible: Always

I don`t know whether this is related to the ksoftirqd problem, but my external keyboard could not be recognized after the ksoftirqd problem had emerged although I have plugged it a dozen of times on multiple USB boards. i.e. The disk load problem had already been gone, but the USB keyboard was not recognized afterwards any more. Problems with the recognition of my USB-mouse or keyboard can normally be resolved by plugging them in once another time.
Comment #2: invalid; accidentially plugged in wrong device.
Created attachment 319136 [details] same info for 100% cpu no disk acces ksoftirqd-hang This time there was no disk access but a 100% CPU-load. In a fact nothing seems having changed since the times of OpenSuSE 11.1.
THe 11.1 one hasn't fixed yet, so I don't see a reason to have 2 bugs. *** This bug has been marked as a duplicate of bug 465039 ***
It was possibly already fixed in the meanwhile since I have never experienced this with kernel 2.6.30.
