Thank you for these hints!
I updated the microcode (dmesg reports an update from version 0x10 to 0x1e) as well as setting the tunables. At first I only disabled PCID; the "nvme0: async event occured" continued to pop up, thus adjusted the rest of the tunables, too. The messages still continue to come in. But I will wait and see if the system panics again.
PS: it seems I was ignorant to see the read me - apologies.
