full dmesg
kernel: 3.19-rc4
hardware: Thinkpad T510, Quadro NVS 3100M
full dmesg attached, nouveau parts below
What I did:
1. downclocking before starting X
-> '[0000:01:00.0] invalid/missing rammap entry' in dmesg
2. start X
-> working fine (could run glxgears, didn't try much else)
3. returning to default performance level
-> fine
4. downclocking again
-> lockup, broke it with sysrq and saved dmesg
Any other logs I should produce?
Do you want a more verbose dmesg?
