[flashrom] Flashrom stuck using 100% cpu while probing for a chip

[GatoLoko]

I've tried to run flashrom -V to see if it could identify the chip on my
new board (AsRock M3A-GLAN), and it got stuck while probing for the
first chip.

I've tried commenting out that specific chip (AMIC A25L05PT) and then it
gets stuck on the next one. Then commented out all AMIC chips, and it
got stuck on the next one (the first ATMEL on the list)

I've tried with an older flashrom (0.9.2-r1141). It skipped some AMD
chips, then got stuck on AMIC again.

Talked with "tlt" and "stefanct" on irc and they asked for a strace and
a gdb backtrace. Strace produced no results. Gdb log is attached.

"stefanct" tried and reproduced it on a machine with nicintel_spi, but
warned it was with an unsupported nic:
