I guess I should recompile the kernel and test again. :( I also experienced a high load under Lenny, but IIRC this showed up under an older kernel (2.6.18), too (after X server is started, standard installation, no additional packages). > Haven't had time to try to localize the problem.

Could that be the problem with kernel 2.6.25-rc8? Thanks! Gerhard -- Psssst! Schon vom neuen GMX MultiMessenger gehört? Der kann`s mit allen: http://www.gmx.net/de/go/multimessenger
