Yes, I can't confirm the bug either. I only have lpc tis devices, so it could be something to do with spi, but when I do
python3 in one shell
>>> fd = open("/dev/tpmrm0", "wb")
do rmmod tpm_tis in another shell
>>> buf = bytearray(20) >>> fd.write(buf) 20
so I don't see the oops you see on write. However
>>> fd.close()
And it oopses here in tpm2_del_space
