Are you sure is not an hardware failure? Disk? Ram (try memtest)? Is a real server with IPMI and hardware logs to have a look at?
Seems not a boot (grub...) issue to me, but a more severe (HW) one.
Or try in chroot to install and updated kernel / reinstall the one you are using, maybe it's corrupted. Or record with your cell phone the boot procedure and messages and try to discover what are the first problems are shown (this kernel panic could be a result of some previous error/s)
Sorry, just my cent.

I run HW test (Dell bios support that) and everything is OK
I can boot live distro and it works fine
Then I chroot to proxmox and install the same kernel (dpkg -i pve-kernel-4.10.17-2-pve_4.10.17-19_amd64.deb) and no luck - the same error.
 
Can I reinstall proxmox without loosing virtual machines? I copied /var and /root directories to external drive.
Originally root file system (/) was /dev/mapper/pve-root

I think you can try to remove all proxmox packages and reinstall, BUT don't run the iso installer, that will delete all disk content.
In any case you MUST HAVE a backup on external driver, if you don't there is a not trivial procedure depending on the type of storage you have (normal recent > 5.x installation? Then probably your Vm are in a thin-lvm logical volume, so you have to "dd" them, also have to save /etc content, but in any case I'm writing here to stop you from thinking of being able to save your vm without a proper backup on external storage and knowing what you are really doing).
So please try to record with your cell phone the boot messages, try to boot with an older kernel (initial blue boot menu, choose "advanced options for..." and then previous kernel) and report back.

Thank you for advice.
I managed to get all VMs working. I have some additional disks in this machine so I resized one partition, on free partition I installed debian, then proxmox in debian, and I added all VMs, changed conf files to point to LVM.
I still have lvm boot partition - strange but I can't find anything on that partition (ex boot) inside /etc/pve (i.e. I can't find old conf files).
Anyhow thank you all for help.
