BTW, TCG looks like the right place where the bug was, because it affected other targets and machines. This is the actual list of tests I was seeing the same issue (and are now fixed): (1/4) tests/acceptance/replay_kernel.py:ReplayKernelNormal.test_aarch64_vir= t: PASS (8.86 s) (2/4) tests/acceptance/replay_kernel.py:ReplayKernelNormal.test_arm_virt: PASS (13.42 s) (3/4) tests/acceptance/replay_kernel.py:ReplayKernelNormal.test_m68k_mcf520= 8evb: PASS (3.20 s) (4/4) tests/acceptance/replay_kernel.py:ReplayKernelNormal.test_xtensa_lx60= : PASS (12.29 s) Cheers, - Cleber.
