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 root@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 conection issues). Also, everytime 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.] And that's about it. In particular, nothing shows in /var/log/messages. As for the panics, I'm clueless. 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 funny to have these kind of problems while doing some work. Any help would be appreciated, if nothing else, to understand what's happening. Thanks!
