    SubjectRe: [tpmdd-devel] tpm_tis driver failed to suspend, error -62
    Sending again, plain text.

    ---

    Hey Aaron,

    Sorry for the delay. Can you send us the dmesg output after setting
    loglevel=7 at boot time? Additionally, can you send us the TPM
    manufacturer model/version?

    # cat /sys/devices/pnp0/00\:0*/caps

    Adding Kent.

    Cheers,
    Rajiv
