27 |

28 |
I can't restart X, it hangs when I try, xrandr also hangs. Even kill -9 |
29 |
doesn't kill it. The logs sometimes don't show anything at all but today it's |
30 |
show this consistently: |

On one occassion there where about 20 backtraces on the log. That log is gone |
64 |
but it had a message basically saying (I don't remember the exact words) that |
65 |
something went wrong and the kernel recovered but a reboot was still needed. |
66 |
I'll post if it comes up again. |

Also relevant that I've been getting this and similar errors on my logs for a |
69 |
few days (probably since I switched to the radeon driver), all the i2c devices |
70 |
are on the video card: |
