Btw I don't know if it is related to this issue, but sometimes I also get this error :
411.265798] nouveau E[ PFIFO][0000:02:00.0] DMA_PUSHER - ch 2 [Xorg[1108]] get 0x00200358c4 put 0x00200358e0 ib_get 0x000000cc ib_put 0x000000cf state 0x80000000 (err: INVALID_CMD) push 0x00400040 After that my thinkpad usb keyboard stops working. There is nothing logged about it though except for this nouveau error. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1097178 Title: nouveau failed to idle channel 0xcccc0000 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-quantal/+bug/1097178/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
