Comment 8 for bug 1865570

@kaihengfeng, unfortunately that does not work.
I could not find time to do git bisect (each kernel build takes a long time), but it would not help if I did. I did a "bisect" over the packages in https://kernel.ubuntu.com/~kernel-ppa/mainline/. The problem is, between the version with working suspend and the version with suspend that only works once, there are several version in which suspend instantly hangs the system:

5.4.24-050424-generic suspend works
5.5.0-050500rc1-generic kernel freeze on the first attempt to suspend
5.5.0-050500rc4-generic kernel freeze on the first attempt to suspend
5.5.0-050500rc5-generic kernel freeze on the first attempt to suspend
5.5.0-050500rc6-generic kernel freeze on the first attempt to suspend
5.5.0-050500rc7-generic suspend works only the first time
