Hello
I've got Radeon HD 7870 XT running under arch linux. It works fine on catal=
yst
drivers, but fails on OS driver.
Without patches from this bug (patch 3&4 or 5) my computer hangs. Signa=
l to
monitor is off and monitor suspends, logging through ssh is impossible, sys=
tem
logs are cut before launching X.
After applying patch (3&4 or 5) screen goes black, but monitor doesn't =
go to
suspend. I can log in with ssh, after killing Xorg.bin console is visible a=
nd
operational. Aftr killing X kernel logs show=20
