The non-verbose kernel log
Steps to reproduce:
Boot linux with NV04 card in motherboard AGP slot.
OR
'modprobe nouveau' with NV04 card in motherboard AGP slot.
Actual Results:
2 times during the boot process the screen turns black, only to return back to
the character display. The nouveau module ends up loaded, but the screen
appears to not be using the drm driver.
Platform:
Alpine Linux 3.10.1 Standard, kernel 4.19.58 (non-verbose log)
Tiny Core Linux, kernel 4.19.10 (verbose external module log)
I tried using the kernel parameter nouveau.config=NvMSI=0, but it made no
difference. I also tried using nouveau.config=NvBios=PRAMIN, even though there
were no "checksum invalid" errors in the dmesg output.
I was unable to get a VBIOS dump, as the /sys/kernel/debug/dri folder was
empty.
I was also hesitant to do a git bisection, as compiling the nouveau kernel
module takes upwards of 7 hours on the machine I am using. However, I can try
if you would like.
I have two kernel logs, one is from kernel 4.19.58 and has nouveau compiled as
an in-tree module. The other log is for kernel 4.19.10 and has nouveau compiled
as an out-of-tree module, but I was able to add the kernel parameters
drm.debug=14 and log_buf_len=16M.
I apologize if I left any information out, and thank you for any reply.</pre>
