You happen to know how I get more verbose-debug outputs?
You have...
[ 57.320031] kernel BUG at block/blk-core.c:2981!
[ 57.320031] invalid opcode: 0000 [#3] PREEMPT SMP DEBUG_PAGEALLOC
Me has...
[ 1263.965989] Kernel BUG at ffffffff81328b2b [verbose debug info unavailable]
[ 1263.966022] invalid opcode: 0000 [#1] SMP
CONFIG_DEBUG_PAGEALLOC=y ?
Block-specific debug settings?
$ egrep -i 'block|blk' .config | egrep -i 'debug|dbg'
# CONFIG_DEBUG_BLK_CGROUP is not set
# CONFIG_DEBUG_BLOCK_EXT_DEVT is not set
