RE: [Xen-ia64-devel] Stability has improved but there is still work tobe done.

["Magenheimer, Dan (HP Labs Fort Collins)" <dan.magenheimer@xxxxxx>]

I started a test run of xen-unstable cset 9922, and
accidentally only fixed half of Anthony's patch --
I added the st4 in xenminstate.h but forgot to move
the call to handle_lazy_cover in process.c.  (I also
didn't use your tlb_pte cleanup patch.)  I am now
up to 86 linux compiles.  I wonder if that one line
addition (st4) is really all that is required to
fix the "gcc segfault" bug?

Tristan, since you have a fast machine, perhaps you
could also try just that one line fix?

Thanks,
Dan
