Default No card initialization with "warm" reboot

When trying to do a "warm" reboot with kexec-tools (ie. after shutdown there is no BIOS and bootloader screen, the system goes straight to loading the kernel) my main graphics card isn't properly initialized. I have to do a proper reboot or complete shutdown to have my card back.

The thing is that this feature worked until about a month ago, but unfortunately I can't remember exactly when/how it stopped working. Bug report attached.

Thanks

Did you upgrade the driver, kernel or any user space tools since it last worked?

Does it work if you unload the nvidia module before the kexec jump and load it again after?

Hm, doesn't it require (re)loading the nvidia module anyway, since it's built against the current kernel? (i.e. the "old" nvidia module won't work with the new kernel you want to kexec to)

Yes it started after a kernel upgrade with or without an nvidia driver upgrade, unfortunately I can't remember exactly.

This problem occurs even if there is no kernel change.
