BUG booting 2.6.26-1-iop32x on Thecus N2100
Hi,
I finally got around to putting a serial port onto my semibricked N2100
and got a log of the boot. Attached is the full log, the interesting
line is:
[42949526.360000] BUG: scheduling while atomic: swapper/0/0x00000100
:(
I'm going to try an flash an older kernel and hope that fixes it now...
Cheers,
Ross
