The following reply was made to PR kern/41065; it has been noted by GNATS. From: Nate Lawson <nate@root.org> To: =?iso-8859-2?Q?Marcin_Liwi=F1ski?= <gospos@tekkom.pl> Cc: freebsd-gnats-submit@freebsd.org Subject: RE: kern/41065: time counters gives negative time, system hang-up Date: Fri, 11 Oct 2002 22:08:40 -0700 (PDT) All I know is that the HPT366 hangs and times out in UDMA66 mode but not UDMA33. This may be timing dependent and adding another CPU changes the timing. This is just a guess. In any case, the workaround is sufficient for me to run a BP6 in -STABLE and now works for you. -Nate On Thu, 5 Sep 2002, [iso-8859-2] Marcin Liwiński wrote: > hi, > > it works for now, but i wonder: why this problem apear just after i added > the second cpu ? > > -- > with best rgrds, GoSPoS. > The BOFH. > > > > -----Original Message----- > > From: Nate Lawson [mailto:njl@FreeBSD.org] > > Sent: Wednesday, September 04, 2002 12:30 AM > > To: gospos@tekkom.pl; njl@FreeBSD.org; freebsd-bugs@FreeBSD.org > > Subject: Re: kern/41065: time counters gives negative time, system > > hang-up > > > > > > Synopsis: time counters gives negative time, system hang-up > > > > State-Changed-From-To: open->feedback > > State-Changed-By: njl > > State-Changed-When: Tue Sep 3 15:27:51 PDT 2002 > > State-Changed-Why: > > The HPT366 controller on bp6 mobos has known problems.
