Sa= me problem with 10.3 or 10.4 user land, so simply upgrading the kernel triggers the issue. For example, I cannot login as myself on the console, or if I login as root= and try to su or sudo myself, the tty hangs (CTRL-C usually does nothing, CTRL-T shows [sysctl mem], and I have to login via another virtual tty. Sadly ther= e's nothing appearing in /var/log/all.log when the deadlock occurs. Another command that causes a hang is "killall -HUP syslogd" when logged in= as root. For additional information, see the similarly titled thread on freebsd-stab= le. Kernel boot log: http://www.knigma.org/scratch/010418.10.4.txt I created the following kernel dump shortly after a normal boot (booting ha= sn't been affected so far), and then immediately trying to login as my normal us= er and hitting Ctr-Alt-ESC after the tty hung. CTRL-T showed [sysctl-mem]. Ker= nel dump created with "call doadump": http://www.knigma.org/scratch/core.txt.0 http://www.knigma.org/scratch/vmcore.0.gz http://www.knigma.org/scratch/kernel.debug.gz Motherboard is running the latest BIOS and system has been rock solid on 10= .3 for months.
