Notebook: Acer Aspire 5739G
VGA: GT240M DDR3
1) when was used old nvidia driver, this issue showed up after logout or console switch (and continue into X)
2) lastest nvidia driver doesn't act like this, but after switching back to X freeze.
System init is ok, after nouveau load screen is stable for 2 second, after that blink and start trembling until shutdown/reboot.
dmesg is located at http://pastebin.ca/1801344 , I don't have it locally. I will attach it soon to bug report.
My own old bug. Closing, I guess Nouveau works correctly these days.
