This is a pretty bizarre crash to tell you the truth. It occurred during execution of a userspace program, doing a syscall to kernel space. There's a bunch of userspace addresses in the registers, stack and the faulting address, and the call trace has consecutive syscalls, and we fault in some general cputime accounting. I'll have a look, but in the meantime, are you interested in testing the 5.19.0-15-generic kernel that just came to Kinetic, instead of the mainline 5.19.3-051903-generic kernel you were using?
