Re: [SOLVED] Random short pause for second of amd cpu

I think these two problems which would both happen in the same boot are not quite same, and this problem still exist after limiting cstate.

By the way, would anyone have better idea about blocking tpm? I'm not sure about whether `module_blacklist=tpm` would work as I have mentioned above.

Re: [SOLVED] Random short pause for second of amd cpu

lsmod|grep tpm

But I'm fairly sure that the module won't load w/ that parameter.

You cacould also disable secureboot in the firmware, but that's rather unrelated to any kind of stutter in the OS.

6.4.11 disabled RNG for all AMD fTPMs and changed tpm_tis to Opt-in interrupts https://cdn.kernel.org/pub/linux/kernel … Log-6.4.11

Solved. It seems to be no more stutter after update.
