can you please provide more details?
Valuable information would be:
Kernel Version (output of uname –a)
Ubuntu Version (output of cat /etc/lsb-release)
Output of dmesg in error and non-error case?
When I first boot the ubuntu ,the tpm_tis module works well.But if I reboot the OS,tpm_tis prints "tpm_send: error -2" message.
Who can help me solve this problem?
