Architecture: x86_64
Machine: amd64
 Description:

On one system I have with an nvidia geforce 1050 ti, with a GENERIC
kernel from 9.99.95 and also from yesterday, during boot there is the
"blank" moment where it tries to enable the graphical console.

But after that blank, it goes back to text console and the kernel log
messages stop. I guess they continue on the graphical console (that is
however not visible to me) since the boot finishes and I can login
with ssh.

/var/run/dmesg is not very interesting though, it consists of:

# uniq -c dmesg
   1 fo: SCHED_ERROR 20 []
 369 nouveau0: autoconfiguration error: error: fifo: SCHED_ERROR 20 []
   1 nouveau0: autoconfiguration error: error: fifo: fault 01 [WRITE] at 000000000027e000 engine 04 [BAR1] client 08 [HUB/HOST_CPU_NB] reason 02 [PTE] on channel -1 [103fe6e000 unknown]
 437 nouveau0: autoconfiguration error: error: fifo: SCHED_ERROR 20 []

On the "text" console the last lines I see are nouveau:

nouveau0: info NVIDIA GM204 (124020a1)
nouveau0: info bios version 84.04.31.00.06
nouveau0: interrupting at msi9 vec 0 (nouveau0)
