Gnome hangs at boot with 7.4 and AMD Radeon R9 M265X

[Jean-Michel Dubois]

Hello,

Yesterday I install last updates on a Toshiba Satellite P50B-10D with AMD Radeon R9 M265X graphics adapter. Now kernel is 3.10.0-693.2.2. Since then Gnome startup hangs. Text sessions (Ctrl-Alt-Fn) display a text cursor but are hanged too.

I switched to multi-user.target, logged as root and run startx. It displays a grey screen with the mouse pointer. Text sessions can be activated as usual.

systemctl isolate graphical.target hangs too.

Thanks in advance for your help.

[   23.236191] [drm:r600_set_pcie_lanes [radeon]] *ERROR* invalid pcie lane request: 7

Before September 21 version number was 2.43.0 20080528. There was no ERROR line. How could I rollback to V 2.43.0 ? I tried to undo the last update but it seems that it is not possible because previous packages are not available.

In dmesg I did not notice this message :

[drm:r600_set_pcie_lanes [radeon]] *ERROR* invalid pcie lane request: 7]

Any idea ?
