I've met kernel hang-up without any stack trace from kernel 5.7.6

journalctl(It said that its data was corruption after rebooting). Is there any method of
collecting debug information in this situation?
Not after the fact.
Environment:
* Fedora 32 x86_64
* Kernel
* 5.7.6-200.fc32 @updates-testing?
* 5.7.7-200.fc32 @updates-testing
* 5.7.8-200.fc32 @updates-testing
* 5.7.8-200.fc32 (debug build)
* External modules
* nvidia 440.100-1.fc32 from rpmfusion
* zfs 6f1db
But kernel developers are not going to be interested anyway because you
have out-of-tree drivers, particularly the nvidia one.
