Kernel 5.6: system freeze when resuming from suspend or hibernate

Starting from kernel 5.6 on my ASUS N56VB laptop (GeForce GT 740M) I can not resume from suspend or hibernate if nvidia driver (440.82) is installed. If I suspend from desktop, screen goes black when resuming and no input works. If I suspend from another tty, then upon resume I can see previous text, bit can not input anything, I can switch to another tty using Ctrl+Alt+Fn, but other ttys are also frozen, and that’s the only combination that works, even Ctrl+Alt+Del doesn’t. The only option is to hard-reset. Journalctl or directly inspecting /var/log/messages do not yield anything useful, no new lines after:
kernel: PM: suspend entry (deep)
kernel: Filesystems sync: 0.145 seconds
This does not happen in kernel 5.5.18, only in 5.6 (tried 5.6.6, 5.6.7, 5.6.8).
OS: Fedora 31 x86_64

I managed to get some log from journalctl having configured nvidia power management services:

Tested again with kernel 5.8.17, because I saw that some PCI bug related to nvidia was fixed in that kernel: https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.8.17 (search commit b6bd62dc59e7af25a0b1af432a553c0f504ce64c). However problem persists with the same trace log.
