Hi, Kernel updated to: kernel-2.6.36-0.34.rc6.git3.fc15.x86_64. Same issue. Martin Kho Hi, Kernel updated to: kernel-2.6.36-0.35.rc7.git0.fc15.x86_64. Issue still exists. Btw. For now I disabled desktop effects. This is a temporary work around. Martin Kho Hi, I picked kernel 2.6.36-0.36.rc7.git3.fc15.x86_64 from koji. Desktop effects with the XRender backend (KDE) are functioning again, thanks. But there are still a bunch of nasty messages in the output of dmesg. I'll attach them, may be nice to have :-) Martin Kho Created attachment 453108 [details]
dmesg
[ 60.426367] [ INFO: HARDIRQ-safe -> HARDIRQ-unsafe lock order detected ] [ 60.426380] 2.6.36-0.36.rc7.git3.fc15.x86_64 #1 [ 60.426389] ------------------------------------------------------ [ 60.426401] kwin_opengl_tes/1706 [HC0[0]:SC0[0]:HE0:SE1] is trying to acquire: [ 60.426414] (&(&mm->unused_lock)->rlock){+.+...}, at: [<ffffffffa0036394>] drm_mm_put_block+0xf6/0x12a [drm] [ 60.426454] and this task is already holding: [ 60.426466] (&(&dev_priv->context_switch_lock)->rlock){-.....}, at: [<ffffffffa0092502>] nouveau_channel_free+0x11a/0x23e [nouveau] [ 60.426501] which would create a new lock dependency: [ 60.426511] (&(&dev_priv->context_switch_lock)->rlock){-.....} -> (&(&mm->unused_lock)->rlock){+.+...} Hi, For me, the issue is solved after updating to: * xorg-x11-drv-nouveau-0.0.16-11.20101026git1143e7a.fc15.x86_64.rpm * libdrm-2.4.23-0.1.20101108.fc15.x86_64.rpm These will be pushed with the next rawhide update, I suppose. Thanks for the good work and please close this report. Martin Kho Note: There are two harmless (?) messages: [ 63.899519] [drm] nouveau 0000:01:00.0: unknown parameter 15 [ 63.899937] [drm] nouveau 0000:01:00.0: unknown parameter 16 Thanks for letting me know! Yeah those messages are harmless, the 2D driver is querying the kernel if it supports certain features that aren't yet in the rawhide kernel. They'll make it there at some point, but things will work correctly regardless. |
