Hello again! I am having an issue with FreeBSD 6.1 on a laptop, a Dell Inspiron 700m. You may remember me from Autumn of 2004 trying this with 5.2.1 and having troubles... Or not. Anyway, I was told that 6.x was working on this hardware, and I tried it, and it was great! Until I put in the 2nd Gig RAM card. :-( That consistently yields: busdma dflt_lock and a forced reboot. I can take out the RAM card, and life is good. I can put in the RAM card, and leave the network cable unplugged, and life is good. I've run memtest for 9+ hours and 7 Passes with 0 errors, with the 2nd RAM card, so it's almost-for-sure not the RAM itself, right? I can put in the 2nd RAM card, leave the network cable unplugged, and run for awhile. Then I plug in the network cable, the bfe device tries to come up, and "BaM!": dusdma dflt_lock forced reboot crash I can do all the above several times over, with the exact same results. I've re-installed FreeBSD, just in case, with a pretty minimal install: base, man, ports dir, and the other required bit I cannot recall now... kernel? I did not do anything funky like SMP or anything. I did use "Custom" install, as I'm a custom a la carte kind of guy... I've got a vmcore.0 dumpdev/savecore output file, all 2 GIG of it, or you can get the .gz version, which is "only" 150M, if you want to gunzip it: http://acousticdemo.com/inspiron700m/ I'm also posting any high-level results here for others to be able to use FreeBSD 6.2 on this hardware: http://phpbootcamp.com/articles/inspiron700m2.htm [Note different servers, as the 2 Gig file would not fit on the one, but I didn't want to move the old article...] I'd sure appreciate any help on getting both the 2nd GIG of RAM and the network at the same time, rather than having to choose. :-) Failing that, since I do boot into Windows occasionally for browser testing or Windows-specific software... Is there some easy way of convincing FreeBSD to just completely ignore that second RAM chip, even thought it's in the box? I'm sure I could survive with "only" 1 G of RAM when I boot into BSD, at least in the short term. Actually, I guess I could survive with only 1 G across the board, but I paid big money (for me) for that second Gig... TIA!!! -- Some people have a "gift" link here. Know what I want? I want you to buy a CD from some starving artist. http://cdbaby.com/browse/from/lynch Yeah, I get a buck. So?
