After extensive hardware testing, new thermal compound, new case and a lot of work improving airflow, I'm now confident my new machine is OK from a hardware point of view (a weeks worth of memory testing, days of running prime95, temperature monitoring, extensive sessions with sysutils/stress running from a liveCD). About 20 minutes ago, I booted into the version of FreeBSD I had built previously to try to debug a DRI problem (which turned out not to exist, evidently). The build has every debugging option I could find enabled (WITNESS, INVARIANTS, etc). Upon trying to build the 'lmmon' port, I was greeted with a panic. I was dropped into ddb and thinking that the relevent crash info would be saved, I rebooted. It wasn't saved. The panic is reproducable: it always occurs in vfs_cache.c:345. How can I get all the info I need saved in order to file a PR? thanks, xw
