>Originator: Peter van Dijk
>Release: FreeBSD 4.1-STABLE i386
>Organization:
Vuurwerk Internet
>Environment:
Today's world+kernel (RELENG_4) on an SGI 1200 with 2 PIII-550s and 1GB
of RAM. Crashes occur equally with or without SMP in the kernel.
>Description:
I can do any kind of traffic without problems *except* accepting incoming
connections. Telnetting to port 22 or 23 of the box from another box
crashes the box. Console-switching still works, the box still pings,
new TCP connections are accepted but userland seems completely dead.
A august 25th kernel works, so the bug must've been introduced somewhere
over the last 5 days.
>How-To-Repeat:
cvsup to a /usr/src from today afternoon (GMT) and build a kernel. GENERIC
will do. Telnet to port 22 or 23.
>Fix:
I compiled a kernel on a box that was cvsupped around Aug 25th and
installed that kernel. No more problems. A 4.1-RELEASE GENERIC worked
flawlessly too.
