Hi,
After updating a Leap 15.4 pc I get lots of these messages when I enter dmesg:

[ 6.189361] ---[ end trace 9049d1d3b12fd5d6 ]---
The above message is repeated lots of times.
The new kernel version is 5.14.21-150400.24.84-default.
When I reboot and select kernel 5.14.21-150400.24.81-default, everything is fine as usual.
Is this a bug? I simply wait until the next kernel update?
Thanks!
