Since starting to use the DRI driver I am having problems with my machine locking up. Remote ssh sessions die, keyboard dead, screen blank. I am asking for pointers on how to try and debug this. My system is ZFS on boot so I created a swap partition on USB /dev/da0s1b and added dumpdev="/dev/da0p1" to rc.conf. After rebooting into single user mode and mounting zfs partitions "zfs mount -a" I tried #savecore /var/crash /dev/da0p1 but savecore complains that no core files were found. Is kernel dump to USB swap not supported? I'm running 10.1-BETA1 with these options added. options INVARIANTS options INVARIANT_SUPPORT options DEBUG_VFS_LOCKS I have not been in front of the box during failure so I am not sure if it exhibited the behavior shown below or not. I have used this box for several years using VESA drivers without issue. I'm posting here first since this seems to related to a DRI issue. Thanks. --mikej On 2014-09-12 14:02, Michael Jung wrote: > This has happened twice so I thought I would report it.
