I have same problem on my system with 3 old PCIe NV4B cards. Tested with kernel 3.16.2 and Mesa 10.2.7, with kernel 3.14.11 and Mesa 10.2.2. After boot I have many errors in dmesg nouveau E[ PFIFO][0000:03:00.0] CACHE_ERROR - ch 1 [X[1450]] subc 5 mthd 0x019c data 0x80000010 where "ch" and "subc" are different, but always with 2nd or 3rd card. Everything works well. Then I run any application that uses the GL (for example glxgears). After an interruption of the application system freezes. Then I see few nouveau E[glxgears[1467]] failed to idle channel 0xcccc0000 [glxgears[1467]] in dmesg. I have tried with nouveau.vram_pushbuf=1, but have same errors.
