I can't agree with that. I'm sure PDC on most platforms has some bugs.
But "required" (as defined by HPUX) PDC calls work.
Not using PDC in this case (BTLB init) seems silly to me since it
offers binary compatibility across platforms and archs.
See the parisc-linux.org FAQ on how to update PDC if you suspect someone
has buggy firmware. And reporting PDC bugs here could lead to them being
fixed (depends on severity and machine type) or "clean" workarounds.
