accessing radeon_hd device locks system up
|Reported by:||kallisti5||Owned by:||kallisti5|
Accessing the running /dev/graphics/radeon_hd* device will cause the machine to fully lock up. When you access /dev/graphics/radeon_hd* from the vesa driver, the radeon_hd fully loads and initializes the card as per the logs.
The same behaviour doesn't occur on the vesa device.
cat /dev/graphics/radeon_hd* is enough to make the machine halt.
