Re: [Xen-devel] xen-detect fail.
Hi,
Where the code calls signal(SIGILL, ...) can you try changing it to
signal(SIGSEGV, ...) instead? Could be that some versions of Linux deliver
invalid opcode exceptions as SIGSEGV rather than SIGILL. Would be weird, but
we can handle it if that's what's happening.
Thanks,
Keir
