Since linux kernel 4.14-rc1 almost any I/O has a chance to freeze kernel
(no log in /dev/tty0 nor /dev/ttyS0 not netconsole, no ARP answer over
network) on one of my machines. Compiling linux kernel reproduces the
issue reliably so far.
Bisecting between v4.13 and v4.14-rc1 led me to commit
Also I created a bug in bugzilla, bisect log is attached there:
Unfortunately I can't test reverting of the commit on current mainline
due to revert conflicts and I don't know how to resolve them correctly.
CPU: AMD FX-9590
RAM: non-ECC DDR 12 Gb
Storage layout: btrfs on top LVM on top LUKS on top HDD
