next in thread | raw e-mail | index | archive | help
I'm running 6.3STABLE with an AMD 4850e Athlon X2 and occasionally get
the following message on the console:
acpi_tz0: failed to set new freq, disabling passive cooling
I also see the following 2 messages immediately after devd starts every
time I boot (and which don't appear in any log file):
hw.acpi.cpu.cx_lowest: C1
sysctl: hw.acpi.cpu.cx_lowest: Invalid argument
Should I be concerned about this and, if so, what should I do?
The CPU info from dmesg:
