Re: [Xen-devel] BUG: x86-64 VT crash backtrace

Hi Jun,

here is the x86-64 VT crash backtrace, as promised. I can trigger it within minutes by simply starting up a 64 bit VT domain on a 64 bit system.

The hideously long (but apparently valid) call sequence has overflowed the 4kB Xen stack. Given that stacks are only per-cpu on x86 Xen, I should probably just make them bigger (perhaps 8kB on debug builds, 16kB on non-debug builds). 64-bit non-debug builds already have (almost) 8kB stacks, so shouldn't see this crash.
