Hi all, Based on gonzo@'s suggestion, I'm putting this on the mailing list as posed to the IRC channel. I've been running stable/10 on my dreamplug (armv5te) of late, but I've had a fairly consistent panic happening: login: panic: Lock vm object not exclusively locked @ /usr/src/sys/arm/arm/pmap.c:4610 Of which the backtrace looks like http://hastebin.com/nefuyawohe.avrasm This has been happening just as I've been building ports, so will be hard to pin down on a easy reproducible case. I also need to do some dtrace-ing on what's going on with the kernel during this time, but I'll need to pick up brendan's book for that. I still need to get setup to be able to do a proper savecore on panic, but I do currently have my dreamplug running in kdb. I'll be in IRC as 'konobi' 24/7 if anyone has specific details that they want. I also have other things that I should get on record on the mailing list, but for now, this is the blocker for me. Thanks, --- Scott McWhirter | konobi
