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=3DNvMSI=3D0, but it made =
no
difference. I also tried using nouveau.config=3DNvBios=3DPRAMIN, even thoug=
h 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 t=
ry
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 comp=
iled
as an out-of-tree module, but I was able to add the kernel parameters
drm.debug=3D14 and log_buf_len=3D16M.
I apologize if I left any information out, and thank you for any reply.
