In recent month, the system is in good condition, but today morning,
system crashed and made a crash dump.
I do not have useful information before crash in console.log but I
show:
Feb 7 08:30:00 FOO kernel: start IR DMA 0x40000011
Feb 7 08:30:00 FOO kernel: start IR DMA 0x40000011
The system crashed Feb 7 9:00am, and it is casued by fwcontrol -u 1 -R.
