John, Thanks for the tip. The kernel I'm using was built on the following date (thus, src-all for release=cvs tag=RELENG_4 was cvsup'd about an hour prior to this): FreeBSD pentarou.parodius.com 4.11-STABLE FreeBSD 4.11-STABLE #0: Sun May 28 12:02:42 PDT 2006 [EMAIL PROTECTED]:/usr/obj/usr/src/sys/PENTAROU i386 Which revision of sys/i386/isa/clock.c might have fixed the problem? I only see 1 commit between May 28th 2006 and present: http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/i386/isa/clock.c?f=u&only_with_tag=RELENG_4&logsort=date -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
