The prooblem started after applying the fixes... However I needed to fix commit 1b6e5fd5f4fc152064f4f71cea0bcfeb49e29b8b "drm/radeon: add missing ttm_eu_backoff_reservation to radeon_bo_list_validate" for 3.10 with deleting the ticket parameter from the function ttm_eu_backoff_reservation(). The commit looks like this for the kernel-3.10: diff --git a/drivers/gpu/drm/radeon/radeon_object.c b/drivers/gpu/drm/radeon/radeon_object.c index 0219d26..2020bf4 100644 --- a/drivers/gpu/drm/radeon/radeon_object.c +++ b/drivers/gpu/drm/radeon/radeon_object.c @@ -377,6 +377,7 @@ int radeon_bo_list_validate(struct ww_acquire_ctx *ticket, domain = lobj->alt_domain; goto retry; } + ttm_eu_backoff_reservation(head); return r; } } I'm suspecting this commit as the culprit of the problem. However I cannot verify it because I still cannot forcibly trigger the error.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
