this is with the newest default kernel (3.1) but also happend with previus kernels. file IO ist fine in PCLOS and Vista on the same pc and partitions. any futher steps to debug this?

kernel 3.2 may bring improvements: https://bbs.archlinux.org/viewtopic.php … 9#p1029699

The last time I had an "INFO: task <taskname> blocked for more than 120 seconds." warning it was a bad hard drive that needs to be replaced. Beware.
