Dear all, As described in the issue here: https://github.com/raspberrypi/linux/issues/4228 and here: https://www.raspberrypi.org/forums/viewtopic.php?f=75&t=303564&p=1817702#p1839351 starting with kernel 5.10.XX we encounter a system hang with kernel panic at poweroff or reboot if we have dtoverlay=tpm-slb9670 loaded. Applying the patch proposed here: https://github.com/raspberrypi/linux/issues/4228#issuecomment-804081079 and rebuilding the kernel solves the issue. Please review the issue and provide guidance finding the cause and solving. Kind regards, Paul Enuta
