Contacting directly is fine, that what's normally done, though it's best to copy the mail list, too. Nobody else has reported this and it has been quite a while. So that's a little strange, but not unheard of. Can you enable nmi watchdog and get a backtrace for this? I have no idea how that change could have caused a lockup. It's just doing something for some messages (ones generated internally) that was done on all other messages, so it's really nothing new. -corey > -------------------------------------------------------------------------------------- > commit 8dfca273353b9131dfd82c2720ccd78f89fd44ae > Author: Corey Minyard <[email protected] <mailto:[email protected]>> > Date: Sat Sep 5 17:44:13 2015 -0500 > > ipmi: Start the timer and thread on internal msgs > > commit 0cfec916e86d881e209de4b4ae9959a6271e6660 upstream. > > The timer and thread were not being started for internal messages, > so in interrupt mode if something hung the timer would never go > off and clean things up.
