Abt 2-3 seconds. And I got a ktr dump right after it came back. It can be downloaded here (I guess rt-click and save the link): http://opal.com/jr/freebsd/releng_7-freeze/200801132250-ktr.out When I run schedgraph, all it shows for the whole period is just: CPU 0 irq 17: pcm0 ath0 ath0 taskq that's it. I have a shared irq between ath and the sound. Funnily enough, within a few mins before the freeze, I was just listening to a voicemail (i.e., I ran mplayer on a .wav file), but that was done easily a minute or more before the freeze. I tried repeating that, listening to the file and waiting a bit, but no more freezes. So not sure if this is a possible indication of the cause, or not. It's annoying not to be able to find a way of triggering this problem on demand, though. Anyway, I looked at the other system where I've had long freezes. It has a shared [irq9: pcm0 cbb0++*] and on cbb0 I have an ath card! So there, too, is an irq shared between pcm and ath. On this system, if I find I'm in a long freeze and don't want to be, I've found that pulling the ath card causes an immediate un-freeze. Admittedly, based on the recent days' discussion in this thread, I was more expecting to see moused or powerd or an xorg problem. Oh! Another freeze, right then! This dump shows pcm0/ath0 too, but also a bit more activity just after the return. http://opal.com/jr/freebsd/releng_7-freeze/200801132337-ktr.out This time I was not listening to sound. I was typing this email. Wasn't there a thread about shared irqs here (or maybe on current) recently? -jr --Sig_/h0OJpbEdnTjcm00Mz3rccXe Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQFHiupsls33urr0k4kRAnvcAJ4rSb+b0Py2JFta2u8UkurEQqKZ+ACfT9Vc t5eRQRrY2gt5EGInynUx0Mk= =20vS -----END PGP SIGNATURE----- --Sig_/h0OJpbEdnTjcm00Mz3rccXe--
