Description danny_archer 2014-09-19 16:37:14 UTC
Created attachment 106557 [details] vbios OS: Slackware current X.Org X Server 1.15.2 kernel version 3.16.3 (although I had a similar crash on an earlier version too, probably 3.15) The log is here http://ur1.ca/i7ro4 My computer crashed while booting. This happened to me before once a month or two ago. Both times I switched off the computer and it booted ok after switching it on again. Except for these to cases I haven't experienced any stability issues.

Created attachment 106600 [details] kern.log It happened again. I was able to log in over ssh and poweroff the machine. The consequent boot went without any issues.

I can reproduce a similar issue by unplug and replug in the display cable. I'll attach the crashed log and other dmesg information.

For me the problem disappeared in Linux version 4.1. HTH.
Comment 9 Hans de Goede 2015-08-17 12:27:09 UTC
The code path in question has been rewritten and recent kernels no longer have nouveau_i2c_acquire_pad, closing this.
