--- Comment #30 from Sergii Stepanenko <sergstepanenko at gmail.com> ---
Hello all!
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.
