Can't boot with self built kernel
by sergey pisarev from LinuxQuestions.org on (#53JAY)
Hello!
I am trying to build kernel and boot with it.
What I do:
Create VMware Fusion virtual machine(firmware set to EFI).
Install kubuntu 19.10.
uname -a output:
Linux linuxtest 5.3.0-51-generic #44-Ubuntu SMP Wed Apr 22 21:09:44 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
Acquire kernel sources:
git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git
switch to version 5.6.9:
git checkout -b v5.6.9 v5.6.9
make copy of current config:
cp -v /boot/config-$(uname -r) .config
update .config:
make oldconfig
choose all default values(just press Enter)
build kernel:
make -j4
install drivers:
sudo make modules_install
install new kernel and register it with grub:
sudo make install
after I try to boot with this new kernel I get an error exception in firmware

I am just starting with linux, so I think I made some obvious mistake but I can't find anything similar with google. Any tips and hints greatly appreciated.
