System information (dmesg, lspci, ...)
I have some problems with the new kernel/radeon drivers with my Radeon HD 5650
in my Acer Aspire 4820TG laptop.
The x-server is started but the GUI constantly freezes for a few seconds. It
happens regardles of the running applications.
The kernel reports repeatedly about some issues (with stack traces).
I think this stack traces point to NULL pointer dereferences.
Kernel Version:
Linux version 3.19.0-031900rc7-generic (kernel at gomeisa) (gcc version 4.6.3
(Ubuntu/Linaro 4.6.3-1ubuntu5) ) #201502020035 SMP Mon Feb 2 05:36:49 UTC 2015
First stack trace:
