but I don't see a solution there. It just ends up asking for the line
numbers.
Well, the line is
__cpuid_count(feat->leaf, feat->subleaf,
regs[RTE_REG_EAX], regs[RTE_REG_EBX],
regs[RTE_REG_ECX], regs[RTE_REG_EDX]);
/* check if the feature is enabled */
return (regs[feat->reg] >> feat->bit) & 1; ====> line 173
Maybe this should catch SIGILL?
Hmm, after disabling 2 flags in that function (fast workaround) it continues
with
