Your utrace-ptrace-compat kernel is not the full utrace implementation which the testsuite targets, it is only its `regset' part. Therefore some (all?) of the crashers just do not apply to such non-full-utrace kernels. Even if it would be the full utrace kernel all the crasher problems were already fixed except clone-get-signal which has unfortunately very rare reproducibility. It reproduces probably best on s390. Still it was seen even on x86_64. It is unfortunately very probably your machine just did not reproduce it. crasher testcases are left marked as `crasher' even after their fix as if you run them on arbitrary (possibly old) kernel it may surprise you by its crash. The x86_64-cs vanilla crasher does not apply to you as you run on 32-bit. Sure thanks for the verifications. Regards, Jan
