I tried reproducing it on a readily-available ia64 running a
RHEL5 xen
kernel, and
the command runs OK for me. I'll try it on a bare-metal
ia64 tomorrow
to see if that
makes a difference.
In any case, your patch would skip the vmalloc (region 5)
area
completely, so that's
not going to work. So I need to know why it's failing on
your machine.
Can you
run crash from gdb, and figure out exactly which address
it's failing on?
Thanks,
Dave
