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