Thanks for the quick response.
It turns out I am using the final 2.6.0 release not the beta (my mistake).
When I get some free time I'll take a closer look at what might be causing this problem
and try to come up with a small patch.
Note: I expect this is a PA-RISC problem and not unique to HPUX (i.e. NetBSD on PA-RISC
should experience it too), but I have no real evidence to back that up.
Thanks again for the quick response.
