TPM Interrupt Not Working? Polling Instead When Booting from Bootable USB
Don't Panic: It's Not a Fault
If you're encountering the issue of the Trusted Platform Module (TPM) interrupt not working and polling instead when attempting to boot from a bootable USB drive, rest assured that it's not a cause for concern. This behavior simply indicates that the TPM on your system does not support interrupts.
No Need for Fixes
You do not need to take any actions to resolve this issue. The presence of polling instead of interrupts does not affect the functionality of your system.
Updates and Monitoring
To ensure optimal performance and stability, it is recommended to update your system's BIOS to the latest version. Additionally, make sure that you regularly monitor your system's settings to identify any potential issues.
Historical Context
Prior to kernel 64, the test for working TPM interrupts was not executed correctly, leading to the kernel defaulting to a polling-based mechanism. With the introduction of kernel 64, this issue was resolved.
