Mario is OOO lately, 



[  864.970948] asus_wmi: fan_curve_get_factory_default (0x00110024) failed: -61
[  864.972365] asus_wmi: fan_curve_get_factory_default (0x00110025) failed: -61
[  864.973533] asus_wmi: fan_curve_get_factory_default (0x00110032) failed: -19


The errors show the BIOS broken to get factory default fan curve data.
I would like sugguest to submit support case to ASUS for further help.

The system reset is triggered when system reach critical temperature.

"I noticed that the processor runs at lower frequencies than 20.04, so do the
fans, most of the time at 0 rpm. Temps 50-70 degrees."

Like you said, the frequencies are lower than 20.04 which have no amd-pstate
driver loaded, so the system temperature increasing slower than 24.04 kernel
which has amd-pstate-epp driver loaded.

I would guess the root cause is system fan error instead of amd-pstate driver.
After you resolve the Fan issue, system will not reset any more.

static int fan_curve_get_factory_default(struct asus_wmi *asus, u32 fan_dev)
{
        struct fan_curve_data *curves;
        u8 buf[FAN_CURVE_BUF_LEN];
        int err, fan_idx;
        u8 mode = 0;

        if (asus->throttle_thermal_policy_available)
                mode = asus->throttle_thermal_policy_mode;
        /* DEVID_<C/G>PU_FAN_CURVE is switched for OVERBOOST vs SILENT */
        if (mode == 2)
                mode = 1;
        else if (mode == 1)
                mode = 2;
        // asus_wmi_evaluate_method_buf failed here, it is a broken bios issue.
        err = asus_wmi_evaluate_method_buf(asus->dsts_id, fan_dev, mode, buf,
                                           FAN_CURVE_BUF_LEN);
        if (err) {
                pr_warn("%s (0x%08x) failed: %d\n", __func__, fan_dev, err);
                return err;
        }
.....
}
