New patch release for Linux 6.1DB 6.2: alleviates intermittent stutters after the AMD Auron processor is enabled with fTPM

CTOnews.com, March 14 (Xinhua)-- AMD previously admitted that after enabling fTPM, a firmware-based trusted platform module, the Ruilong processor caused intermittent stutter problems in Win10, Win11, and various Linux distributions.

Linux kernel maintenance members have reverse migrated the fixes in Linux 6.3-rc2 to Linux 6.1.19 and Linux 6.2.6 to fix stutter problems.

This BUG is most pronounced in the Linux 6.1 kernel, mainly after the hardware random number generator (hwrng) enables kernel multithreading (kthread) for untrusted sources. For example, setting the hwrng source to zero mass (quality setting of zero) will trigger.

CTOnews.com reminder: the patch released this time only disables the hardware random number generator on the version of fTPM that is known to have the error, and has not completely cured the stutter problem.
