block: oopses on 4.13.*, 4.14.* and 4.15-rc2 (bisected)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,
	kernels 4.13.*, 4.14.* 4.15-rc2 crash on occasion, especially
on x86-32 systems. To trigger the problem, run as root:

while true
do
        /sbin/udevadm trigger --type=subsystems --action=change
        /sbin/udevadm trigger --type=devices --action=change
        /sbin/udevadm settle --timeout=120
done

(Thanks to Patrick Volkerding for the reproducer).

Sometimes the kernel oopses immediately, sometimes a bit later (less than
five minutes).

The bisection pointed to commit caa4b02476e31fc7933d2138062f7f355d3cd8f7
(blk-map: call blk_queue_bounce from blk_rq_append_bio). A revert
fixes the problem (tested on 4.13 and master).

Some oopses caught while bisecting between 4.13 and 4.12:
