MCE/Hardware errors/Temperature on MacBookAir 4,2

[Nico Schottelius]

Hello,

with the previous kernel compiling a new kernel, I get these
messages in dmesg:

[170745.226310] ieee80211 phy0: brcms_ops_bss_info_changed: arp filtering: enabled true, count 1 (implement)
[170942.965765] CPU3: Core temperature above threshold, cpu clock throttled (total events = 1)
[170942.965770] CPU1: Core temperature above threshold, cpu clock throttled (total events = 1)
[170942.965776] CPU2: Package temperature above threshold, cpu clock throttled (total events = 1)
[170942.965781] CPU0: Package temperature above threshold, cpu clock throttled (total events = 1)
[170942.965785] CPU1: Package temperature above threshold, cpu clock throttled (total events = 1)
[170942.965791] CPU3: Package temperature above threshold, cpu clock throttled (total events = 1)
[170942.966766] CPU3: Core temperature/speed normal
[170942.966770] CPU1: Core temperature/speed normal
[170942.966775] CPU2: Package temperature/speed normal
[170942.966779] CPU0: Package temperature/speed normal
[170942.966782] CPU1: Package temperature/speed normal
[170942.966787] CPU3: Package temperature/speed normal
[171033.962774] [Hardware Error]: Machine check events logged

Shall I consider these informative/warning/dangerous?

In any case, I'm wondering whath the hardware error may be
and whether it's really a hardware error or OS problem?

Cheers,

Nico
