I have reproduced it: qemu-system-arm: /home/rth/qemu/qemu/include/tcg/tcg.h:339: get_alignment_bits: Assertion `(((1 << (10 - 1)) | (1 << (10 - 2)) | (1 << (10 - 3)) | (1 << (10 - 4)) | (1 << (10 - 5)) | (1 << (10 - 6))) & ((1 << a) - 1)) == 0' failed. Aborted (core dumped) You need --enable-debug-tcg for this assert. It's incredibly stupid of avocado to report SIGABRT as a timeout. r~
