The following reply was made to PR bin/2611; it has been noted by GNATS. From: Bruce Evans <bde@zeta.org.au> To: freebsd-gnats-submit@FreeBSD.ORG, mike@outerware.com Cc: Subject: Re: bin/2611: User PPP hangs machine hard periodically Date: Thu, 30 Jan 1997 03:15:48 +1100 >This problem occurs with the GENERIC kernel. We have built our own kernel with normal serial support (the one we currently use) and with the Hayes ESP support enabled. Both cause the failure (although I think it may have been more frequent with the ES P kernel). The link is using a Hayes ESP card configured as COM1. Please use lines shorter than 80 characters. Changes made a couple of months ago trigger a hardware bug in the ESP. See PR 2270. For the sumbmitter of PR 2270, it hangs after every close. Apparently there is a problem even if ESP support is not configured. This should be fixed in 2.2R. Meanwhile, don't configure ESP support (it doesn't really work), and delete the 2 outb() statements in siostop() in /usr/src/sys/i386/isa/sio.c. Bruce
