@Kai-Heng Feng, I've tested v5.3-rc2 and v5.3-rc4 today.
v5.3-rc4 seems to be working fine and v5.3-rc2 has same issues as latest kernels from repo.
Actual behavior of problematic kernels -- interface is actually working on cold boot,
but turns to be unable to detect a link after a several reboots (in 5-10 minutes from initial boot).
