> Hi Bill,
> I did verify the problem described in the mails "tpm2_flushcontext stuck" related to /dev/tpmrm0 with kernel 5.10.
> After sending the command read public:
> 0x80 0x01 0x00 0x00 0x00 0x0e 0x00 0x00 0x01 0x73 0x80 0x00 0x00 0x00
> the poll call in tcti_device_receive does not return when kernel 5.10 is used.
> With kernel 4.19 write for this command did return -1
> Could you please contact Jarkko about this problem.
> Best
