Then looks there are two fix patches acked & tested:

- the patch in this thread
- another one "[PATCH] tty: vt: Fix soft lockup in fbcon cursor
blink timer."
https://lkml.org/lkml/2016/5/17/455

So which one will be pushed to linus?

Not that it's my call, but we may want both; the first as a safety
measure to prevent an invalid cur_blink_jiffies ever being set, and the
second one to actually fix the initialisation of vc_cur_blink_ms (and
address the warning introduced by the first).

Tomi / Greg,

I'd suggest
- applying "tty: vt: Fix soft lockup in fbcon cursor blink timer." to 4.7 and stable[4.2]
- applying "fbcon: warn on invalid cursor blink intervals" to 4.7
- ignoring "fbcon: use default if cursor blink interval is not valid"

Note: the patches don't depend on each other

I applied both recommended patches on top of 4.4.11 for testing, and they
made things a lot better here.

I suggest the second patch should be backported to stable too, might as well
fix this thing for good *and keep the door closed*.
