NVChannel(GL): Graphics channel timeout! still with me.
I can reproduce this crash in 10-15 minutes, its easy, just play a little bit with panels ind photoshop or illustrator (CS3) and tah-dah its there.
Ok, i have to admit, that after the efi update my MBP (2.2 santa rosa) now runs smoother, but this really sucks. Looks like i have the last instance, reinstal system and do not apply leopard graphic update like everybody else.
Is this happening with an external monitor attached only? In that case i would maybe wait onto the 10.5.3 update.
