The OOPS seems to be caused by the PID of the [timer] IRQ-1. However the OOPS message is too long and I can't read the beginning lines on the terminal. The system hangs so I can't scroll back and it's not written to any log. SysRq does also not work after the OOPS. A bit off topic, but how can I capture those OOPSes? I could get a larger screen and a digital camera ;) The lkcd.sf.net patch does not apply to 2.6.29. Running a realtime kernel in qemu does not make much sense, although it may be sufficient to reproduce this OOPS. Is there a way to use USB as serial console using a hub and two computers? I guess I'll need a dongle or sth. Besides would a printk() to a serial port work even if some IRQ handler hangs? Any ideas? links? robin
