With a JTAG-debugger I dumped out the kernel-log message and saw following entries: <4>BUG: unbalanced irq-handler preempt count in timer_interrupt+0x0/0x50! <4>entered with 00010002, exited with 00000000. What could be the reason for that? A racing ? If it true, how I can find it out? BTW, I enabled all debug-options without to get more information's. I know this version is totally out-dated, but it is my current playground to get a deeper understanding and it's a try to fix a problem. Any hints are welcome!
