Product: Drivers
Version: 2.5
Kernel Version: 4.10-rc2
Hardware: x86-64
OS: Linux
Tree: Mainline

A8-7600 dmesg (full)
UVD init fails at boot and and X server starting stops. Terminal works but
rebooting is impossible because of lightdm has hanged. Hardware: Amd A8-7600
APU, Gigabyte F2A88XM-DS2 motherboard, single 4GB ddr3 2133Mhz ram stick. OS:
Debian testing Xfce.
When using X4 845 and RX460 I have same UVD errors at boot, but X starts ok and
the computer works ok.
Adding _netdev to /etc/fstab home partition mount options helps to start X with
A8-7600 (errors still present at boot and shutdown) and with X4 845 and RX460
removes UVD errors completely. Setting #define AMD_MAX_USEC_TIMEOUT to 100 ms
is better value for A8-7600 than 200 ms because 100ms value enables X to start,
see drivers/gpu/drm/amd/include/amd_shared.h.
The same problem is with
agd5f/linux/log/drivers/gpu/drm/amd?h=drm-next-4.10-wip kernel that is in
4.9-rc8 now. When it it was in version 4.9-rc2 the driver did work fine in both
computers. With A8-7600 pc we need to use the stock Debian kernel 4.8 radeon
kernel driver now.
