The following reply was made to PR kern/965; it has been noted by GNATS. From: Bruce Evans <bde@zeta.org.au> To: Denis.Fortin@dmr.ca, FreeBSD-gnats-submit@freebsd.org Cc: Subject: Re: kern/965: 2.0.5 daily crash: multiple frees in if_ppp.c Date: Tue, 23 Jan 1996 08:24:24 +1100 > System crashes a few times a week (2-5) and reboots. This is Most This may be fixed in rev.1.12 (1995/10/30) of spl.h which is in -stable. See also PR 798. > Annoying since the BB-2016 then seems to require a manual "shutdown -r" > about 50% of the time or it isn't properly reset (i.e. the machine > stops answering the phone). This is probably caused by some of the devices on the BB being active at crash time and warm boots not resetting them. The UART IRQs are ORed together, so they must all be inactive or all except one must be disconnected for that one to be probed. Since they aren't disconnected until they are probed, the probes sometimes fail. This was fixed for some multiport boards (probably for BB's and not for AST's) in rev.1.123 (1995/11/29) of sio.c but isn't fixed in -stable. Possible workaround: Repeat all probes by duplicating the block of 16 BB config lines in your kernel config file. Bruce
