Hi:
When I perform "echo mem > /sys/power/state", I got BUG on rs600_gart_set_page, then suspend hangs.
I don't have a camera to log the outputs, the call trace are:
rs600_gart_set_page+0x31 radeon_gart_bind radeon_ttm_backend ttm_tt_bind ttm_bo_handle_move_mem ttm_mem_evict_fist ttm_bo_force_list_clean ttm_bo_evict_vram ttm_suspend_kms radeon_pci_suspend pci_legacy_suspend pci_pm_suspend pm_op dpm_suspend suspend_devices_and_enter enter_state state_store kobj_attr_store sysfs_write_file vfs_write sys_write system_call_fastpath
l *rs600_gart_set_page+0x31 is in writeq, maybe this is a possible use-after-free. Thanks.
