The speeds change quite constantly under a kernel compile workload, but most of the time it's at 2240800 vs cpuinfo_max_freq which is 2801000 > echo xy >/sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq > may be bad workaround. echo 2240800 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq echo 2240800 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq made it survive a kernel compile for me, with an observed maximum temperature of 87 C.
