Remote ssh sessions die, keyboard dead, screen blank. Most Radeon GPU lockups come from the fact we use(d) a version of Mesa too old (9.1.7). Now, for FreeBSD 10.1 and 11-CURRENT, Mesa 10.3.0 is provided (or will be with the next package build) and this version works *way* better for Radeon users. > I am asking for pointers on how to try and debug this.

Is kernel dump to USB swap not supported? Yes it is. You may need to add the following sysctl: debug.debugger_on_panic=0 It should not be necessary with vt(4), but with syscons, this allows the kernel to dump core after an X session was started. -- Jean-Sébastien Pédron [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQJ8BAEBCgBmBQJUQ/D+XxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQ2NzA4N0ZEMUFFQUUwRTEyREJDNkE2RjAz OUU5OTc2MUE1RkQ5NENDAAoJEDnpl2Gl/ZTMZDoP/iH06tijgn2oMeJmRptHo62P luWgTZi5TDnf9pZRndHnheiwiAxilnXyXwiC2+pgyJL/HH3vt9uTGyLQlymfHc2k jpZsbPTqAsDcTEt0vLobDxX6OKzYQfXoPmtSi7qV1HqKDm6fh7dvQW0xcNT+NAwD sEhIyeXng1b5j0BlcuLGr1sh7VkJ8nT24BJxTzEhX5is747Pg9DfxYgJ+yZfOAj2 d1HM4NTVHNp6l2P6NPRSZDjxVCaG6gdOrEzCOSyEW2+d6qKG/fqbdFTlO5BAwwxO ISfmabWMUDYJa3Ario16DGmziqjx6xWTLPN6232CxkA+aT0Navyu/gayrzpFeyAy DzDgb5HM+1YrVZrb6PLG+kR4+dwptU3FUh0ebUW9SV30Xx6AvaQSUhL2yBihiGkP 9X8iYgttz3ywvYGMxylG7AwdHkZ3cNp0o8kzHwNnFYMk2POGZW/Zlrv65QKeFRxm f6Plx9dXcse0Sfnl/XZlVts5twt/LpNiG98EkE5jsR82qRUT4i7X12EFHArTF057 h/e9blBJt/CJl4B021+FhcGvASFMPQhs/F44lVfSmy5t8A0H59TDGEiCCDGjwISk bL75MZGGS9osI5/br4bZaNFXCP7g9J2asD6oYBEyywAi1Gcan1GtvLxcstCkPylk 5ZujTmU54qQE1T1dFrAI =NqJ/ -----END PGP SIGNATURE-----
