Re: [Xen-ia64-devel] RFC: Switch to xlilo now? Or post-3.0?

Alex,

Same happens for me - it seems that something has changed in
xenlinux, since it works okay after substituting a week-old
xenlinux image.

N.B. Dan: this is in the fast system call path, so I don't
expect you'll see it with RHEL3, since the libc is too old
to support fast system calls.
