[Bug 1556726] Re: firefox freezes and blocks the whole laptop when using ubuntu 14.04 LTS on HP compaq 6910 laptop

[Steve Beattie]

Note that your dmesg is full of the following kernel warnings:

[   58.456045] WARNING: CPU: 0 PID: 897 at /home/kernel/COD/linux/drivers/gpu/drm/drm_irq.c:1268 drm_wait_one_vblank+0x1b5/0x1c0 [drm]()
[   58.456046] vblank wait timed out on crtc 0

This may or may not indicate a hardware problem or a problem with the
kernel you're using (which happens to not be the standard Ubuntu
kernel).
