Hi Daniel,
I am working on the same platform and board, emx270 from compulab, and
never found that problem. The only problem I had was with the
monotonic_syscall option you told, but never happened again.
I posted my configuration file back in this ml, search on the old posts
(a post titled "Illegal instruction on arm buildroot"  or similar) and
start from that (just remember to check the monotonic_syscall
option/patch/similar).
If you don't find it, please write me in pvt so I can send you the file
without disturb the ml.
Please, if you solve the problem, tell me if you can make alsa-lib and
alsactl to work (I am experiencing some problem).

Best regards,
