vlad34 opened this issue · 6 comments
Hi,
I updated kernel Raspberrypi OS to 5.10.46 on my raspberry pi 4 (4Go), the reboot cause no signal (not screen) for the TV in console boot mode. (HDMI connection)
I downgrade kernel to 5.10.44 , it's works the signal on the TV.
The problem is with upgrading to kernel 5.10.46.
Good day.
Are you using the kms driver? Any other non-default settings?
When working what resolution/framerate are you using on display?
Can you ssh in when showing no signal and getdmesg output?
Can you identify the first commit with the issue (using rpi-update <hash> with hash from https://github.com/Hexxeh/rpi-update/commits
Please include the content of /boot/cmdline.txt.
I reinstalled the 5.10.46 kernel with rpi-update and I have the problem again
I don't use the KMS driver, I run on the legacy driver, I think...

Thanks,
you are running fkms. this is probably a dupe of raspberrypi/linux#4428.
Can you try with latest rpi-update kernel?
