Hi,
I'm in need of advice. I've recently installed FreeBSD 9.0-RELEASE on my
laptop (a Dell Inspiron 1318) with a good deal of success. However, I've
been experiencing a few hiccups, to say the least. The kernel is the
GENERIC for the amd64 architecture that comes with the installation
images (no funny compilation issues on my part):
$ uname -a
FreeBSD apeiron 9.0-RELEASE FreeBSD 9.0-RELEASE #0: Tue Jan 3
07:46:30 UTC 2012
r...@farrell.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC amd64
Since I've installed it, the system has been freezing for apparently no
reason and, once in a while, rebooting upon a kernel panic. The kernel
panics come in two varieties:
Fatal Trap 9: general protection fault while in kernel mode
Fatal Trap 12: page fault while in kernel mode
I have the dump files. [Concerning the Fatal Trap 12: I ran memtest86+
and everything turned out alright on the memory side.]
As for the recurrent freezing, it seems to me (but this is a hunch) that
it might be related to wireless card issues (since, for what I can
recall, it happens some time after I start having connection issues).
Also, every time I do a "netif restart", the system just freezes after
displaying two lines:
bwn0: need multicast update callback
TODO: need swap
[In order not to raise side issues, I have a fully working LP PHY
Broadcom 4312 (except for these issues), and I have hw.bwn.usedma=0 in
loader.conf---but the freezing thing happens whether it is set to 1 or
0.] A quick inspection to log files reveals some pattern in
/var/log/messages:

===================================
As for the panics, they immediately follow two of the messages above, as
you can appreciate in the quote.
Maybe the following can help (or not!!). In /var/log/messages, the
following two lines keep showing:
acpi0: reservation of 0, 9f000 (3) failed
acpi0: reservation of 100000, 7f56d800 (3) failed
Needless to say, this won't discourage me from using FreeBSD on my
laptop, but it isn't very pleasant to have these kind of problems while
working. Right now, the "workaround" I implemented is to use a Linksys
wireless adapter I had sleeping in its box. However, being able to use
the Broadcom card would be nice. Any help would be appreciated, if
nothing else, to understand what's happening.
Thanks!
