reassign 625805 pm-utils 1.4.1-8 tags 625805 + patch retitle 625805 pm-utils: quirk needed for ATI Radeon Mobility M6 LY on SONY Vaio Z1-RCP thanks
I have found a way to fix this bug by: 1. disable KMS (so that pm-utils' quirk can kick in) 2. add a quirk for this machine model (please see the attached patch) Please consider adding the quirk into pm-utils' SONY quirkdb. I believe a better fix can be done in drivers/video/aty/radeon_pm.c by adding a BUGFIX entry to the radeon_workaround_list[] within the Linux kernel (so that we can keep KMS), but I don't have time to test that because the fix mentioned above already works great for me.
