Hello,
I've been having frequent problems with BETA1 and now BETA2
"freezing".
There is no diagnostic information, nothing in /var/log/messages,
nothing, just a hung interface. I cannot ssh into the machine and it
appears the box ceases to communicate on SSH. A couple of times I've had
screen corruption on the laptop's LCD display.
Every time it hands I'm running Xorg 7.3, Thunderbird, Firefox, pidgin,
and a bunch of xterms.
Is there something I can do to diagnose this issue?

Regards,
Doug

Did you run 6.2 on this machine prior to 7.0? I had similar problems with a desktop of mine that was running 6.2. Every now and then (sometimes days in between) it would freeze in X, corrupt the screen, or at times would just reboot. There was no warning and nothing of worth in any log files. I had a feeling it might have been my video card, so after taxing it really hard with gl apps and noticing artifacts on the screen, I replaced the card. The system ran well for a few weeks, but the problems persisted. Thought at this point it could be faulty ram, so ran each half-gig stick on it's own until the next failure. Both sticks showed failures. So then I moved the sticks out of slots 1,2 and into 3,4... that was 4 months ago and all is well. I guess what I'm aiming at here is that this could be a hardware issue which can be a pain to diagnose. - -- Karol Mroz kmroz@cs.ubc.ca -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFHL5Qyuoug78g/Mz8RAkEzAJ9yzGU1in5lrS3fUO0mfHfzCuYiqQCfRSn3 EkJrTLktOyfNddasgJPA4V8=tbgK -----END PGP SIGNATURE-----

7.0-BETA1 & 2 occasionally freezing, how to diagnose?

I am still not sure what the cause is...some things I've used / tried: I was using gjournal on my 80 GB /usr partition, with a 1.5 journal to ad01sh . I was getting quite often lockups where it seemed the disk subsystem would stall - anything in memory would work, but as soon as disk access was needed, it'd stall too. Rebooting was not an option, as the shutdown watchdog would timeout and stop it. furthermore, I'd have to go into single user and run fsck /dev/ad0s1f.journal every time the laptop would crash. I seemed to have much fewer bad information in the inodes (thanks to the journal), but I was getting 4 or 6 crashes a day. Since I switched away from gjournal, these crashes have completely gone away. since this is my main machine, i cant experiment too much with it. I also had skype-1.4 running . One of its processes was spinning completely out of control , when i wasn't using skype at all (other than receiving text msgs). I sent an email about it to Multimedia.I've since switched back to skype.1.2 and that problem is also gone. But i still get the occasional lockup. I have a feeling it is related to using the sound card : $ cat /dev/sndstat FreeBSD Audio Driver (newpcm: 32bit 2007061600/i386) Installed devices: pcm0: <Intel 82801F High Definition Audio Controller> at memory 0xb0000000 irq 11 kld snd_hda [20071020_0048] [MPSAFE] (1p:10v/1r:6v channels duplex default) Pretty much everytime I'm getting a lockup, i'm either streaming music from my music box or on a skype call. Not much to go by, but there isn't any logs left at all of the crash. It is not a panic (no writing dump to disk when I press enter, Caps-lock is dead, even the Fn key which is bound to the bios is dead). What I have noticed in these cases is that there seems to be a lock up....then, about a minute or so after it, the mouse seems to come back to life...but then there's nothing more I can do - i've waited for over 5 minutes after this with no more results.... Not sure how I can diagnose / test this, but i'm willing to give them a try, time permitting :) thanks!
