Could you also attach a mmiotrace[1] of the NVIDIA binary driver, and another log of nouveau failing with "nouveau.debug=trace log_buf_len=1M" in your kernel boot options. Thanks, Ben.

I have a large system with pretty voluminous boot time messages that are exceeding the capacity of the ring buffer displayed by "xm dmesg" (i.e., the early messages are lost, and I see only the last messages). With a regular, non-Xen kernel, I use "log_buf_len=size" to enlarge the printk ring buffer size, but this boot option doesn''t seem to work for Xen. Anyone have a handy tip for this problem? Thanks in advance. P.S. I also don''t have access to the serial port, so cannot capture the desired output via that method either. __...

Hopefully you still have those kernels handy, as your logs got cut off. Try booting with log_buf_len=100M to increase the "scrollback" buffer (I assume you have oodles of RAM). Or grab the kernel logs from your system. -ilia

...he screen corruption occurs on every boot (booting with nouveau.noaccel=1 for now), and I can consistently work around it by one suspend-resume cycle. To that effect, I've captured kernel message output booting 3.14-rc3 with 'nouveau.noaccel=1 nouveau.debug=trace,DEVINIT=spam drm.debug=0x6 log_buf_len=16M', and performed a suspend-resume cycle: http://quora.org/nouveau-log.txt Ben et al, would some specific register tracing or otherwise help to locate the issue? -- Daniel J Blueman
