bad dmesg
Hardware: Dell Precision Laptop 7710 with Intel HD P530 and AMD FirePro W7170M
(Amethyst XT)
Kernel: 4.6 and 4.7rc1
xf86-video-amdgpu: 1.1.0
Description:
When X is started, it accepts no connections ("waiting for X server to accept
connections") forever.
There is another bugreport over here [1] that has the same problem with the
radeon driver. Dmesg is attached.
The stacktrace seems to be nearly the same:
schedule
rpm_resume
wake_atomic_t_function
__pm_runtime_resume
[amdgpu_connector_dp_detect/radeon_dvi_detect] (output detection)
drm_helper_hpd_irq_event
[amdgpu/radeon]_resume_kms
[amdgpu/radeon]_pmops_runtime_resume
pci_pm_runtime_resume
vga_switcheroo_set_dynamic_switch
vga_switcheroo_runtime_resume
...
