As others have said, you should still have the 5.2 kernel around. Just change
the grub.conf and reboot. It makes no sense to start swapping around hardware
until you've tried to revert the kernel.
That said, we've seen hangs and strange kernel messages on several different
server platforms (HP DL140g3: NMI-related messages logged, HP DL160g5: hangs
semi-randomly) with the new 5.3 kernels. All of these problems could be
worked around by booting with the kernel option "nmi_watchdog=0".
