bz_status_NEEDINFO "
title="NEEDINFO --- - sna: (Haswell) X-server freezes when enabling DP at docking station"
href="show_bug.cgi?id=71267">bug #71267</a>
- kernel v3.13.0-rc1 + udelay(500) (see <a class="bz_bug_link
bz_status_NEEDINFO "
title="NEEDINFO --- - sna: (Haswell) X-server freezes when enabling DP at docking station"
href="show_bug.cgi?id=71267#c29">bug #71267, comment #29</a> and <a href="show_bug.cgi?id=72314#c32">comment
#32</a>)
(As stated in the initial bug udelay() has to be raised to 500. Todd wrote that
300 might be okay. So, 500 is far above this. Hopefully the 500 doesn't cause
this bug as a side-effect.)
When plugging in the monitor at one DP of the docking station it takes up to
24s (shortest was 3s) until it gets activated (the console cloned to it).
In this attachment I've replugged the monitor 5 times, log timestamps are:
1. 30-33 ... 3s
2. 74-85 ... 11s
3. 184-203 ... 19s
4. 238-262 ... 24s
5. 303-310 ... 7s
As of this I wouldn't call it a bug - the monitor gets activated finally.
Therefor I've set the priority to "lowest".</pre>
