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:

Hi Jens,
I can reproduce this issue every time by forcing bounce on virtio-scsi
and enabling NEED_BOUNCE_POOL.
After applying your patch, there is still kernel oops[1].
I traced it a bit and found the following patch[2] makes a difference by
getting rid of copying iov_iter, but I guess this one is related with
the gcc(6.4.1 20170727).
Even though both your patch and the patch of 'bio_copy_to_iter: get rid
of copying iov_iter' are applied, there is still another oops[3].

Hi Michele,
Please test the patches I sent out and see if it fixes your issue. In
my environment
the two just works fine.

I can confirm these fixes the issue on my system (tested on top of
4.15-rc3), thanks!
