Thanks for your reply.
I have a GTX 1080 and 495.44 drivers.
The crash happens just after the same warning as you.
I'm running the 5.15 rc6 kernel without issue.
The boot problems started since 5.15 rc7 upgrade , and the only differences between this
versions are :
- Enable CONFIG_FAIL_SUNRPC for debug builds (Justin M. Forbes)
- fedora: Disable fbdev drivers and use simpledrm instead (Javier Martinez Canillas).
So i will try to build the kernel without the second patch and make a try.
Thanks again.
