I have written the M8BRS2000 frontend, which has been on test for the
last two weeks.

Unfortunately, on Friday my device has partially failed, in that the
m8brs2000 chip starts to fail with prolonged use.

It seems to be an heat issue as cooling the device restores normal
operation. I will do some more tests in a lab this week for dry-joints.

Have you or anyone else noticed any similar problems running the device
under Windows?

This means the device driver for Linux is back on Alpha and cannot be
released.
