[Soekris] net6501 Machine Check Exception

[Peter Neubauer]

I have my new net6501 (1.40h BIOS) running Debian Squeeze with the 2.6.39 kernel from squeeze-backports.  Shortly after boot while idle, the system consistently reports machine check exceptions (MCE).  The system continues running, although I have separately observed some unexplained segfaults, file system corruption (seemingly wiping out the partition table), and one instance of I/O error (a DMA write error to the SATA SSD).

Has anybody seen similar problems?  Any recommendations?  Should I try a different kernel or distribution?

Here's a MCE log:
