dmesg from a boot.

PDISP error filling the dmesg. It's quite spammy but other than that the X works (GDM loads fine).

Using Archlinux up to date.

Comment 1 Leonidas Spyropoulos 2015-07-22 08:44:20 UTC 
I'd like to add to this that X server crash after 1-2 days running, logs is filled with errors but can't catch them as the pc is unresponsive. Only thing that works is SysRq commands and hard reset.
Comment 2 Ilia Mirkin 2015-07-22 18:27:47 UTC 
You should see if the patch at https://bugs.freedesktop.org/show_bug.cgi?id=91333#c11 helps you at all.
Comment 3 Leonidas Spyropoulos 2015-07-23 08:29:26 UTC 
This seems to remove all the logging in journal. I will keep an eye and see if the pc crash after 1-2 days as it used to.

Thanks
Comment 4 Leonidas Spyropoulos 2015-08-11 08:12:20 UTC 
The patch proposed from Ilia works fine. I see this is released with 4.1.5 I'll consider this resolved.
