2.6.29-rt1+ irqbalance = OOPS

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

Starting the irqbalance daemon ( http://www.irqbalance.org/ ) on
2.6.29-rt1 causes the system to OOPS and freeze. irqbalance works fine
with previous realtime kernels (2.6.24.7-rt27).

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?
