Re: 295.53: the kernel needs "acpi=off", thinkpad T420, nvs 4200M
Hi, a new discovery.
If I boot the kernel with "maxcpus=0" to disable the SMP activation entirely, the whole system could run normally.
Hmmm.....This caused a new problem, there is only one cpu in use. and its temperature is about 64.0°C, not a good news.
