The crashes usually happen in the scheduler. Here is a typical stack trace:\r\n\r\n[ 6478.341912] BUG: unable to handle kernel paging request at 0000000380650980\r\n[ 6478.526633] Call Trace:\r\n[ 6478.529093]  [<ffffffff81004ad3>] __schedule+0x2c3/0x970\r\n[ 6478.534410]  [<ffffffff810051c0>] schedule+0x40/0xb0\r\n[ 6478.539376]  [<ffffffff810b7fde>] worker_thread+0x37e/0x640\r\n[ 6478.551492]  [<ffffffff810c1be6>] kthread+0x126/0x130\r\n[ 6478.570919]  [<ffffffff81910dba>] ret_from_fork+0x9a/0xd0\r\n\r\nPresumably this happens due to stack overflow, since kasan slightly increases stack consumption. We need to slightly increase stack size when running under kasan."}}
