It looks like sometimes the erase command doesn't get through to the
chip. We try two different erase methods, first erasing 4K blocks and
then we try erasing 64K blocks. The whole process only fails of both
erase methods fail (i.e. you get "ERASE FAILED at 0x...." twice). Thanks
for the logs, we have to check what we can find in flashrom. Some thing
you could try is: Do you get the random failures also in single user
mode? There might be something performing concurrent access to the flash
chip (like some ACPI stuff) or interrupts causing too high delays
between flash access cycles make write commands not recognize. Having no
background tasks mitigates the latency problem.
