My E8450 is rock stable. Nothing to complain about. It is still not known what the root cause of the reported boot or reboot problems is.
In a hope to retain my reboot and boot stability regarding the problems of others I followed the report to raise the min_freq clock speed to 600 MHz
This is just one line in /etc/rc.local
echo 600000 > /sys/devices/system/cpu/cpufreq/policy0/scaling_min_freq
Nothing obscure about this tweak. And only precautionary since I do not experience boot or reboot problems with my device at all, even after a lot of 23.05-Snapshot and RC release sysupgrade related reboots.
If the reports make you feel insecure about the device and you don't already own it: don't buy it. I would still buy it because it's still a great value to me and of course stable.
The alternative to me would be Netgear WAX206, which is currently out of stock everywhere. Or GL-MT6000, which is more expensive, bulkier, should have higher power consumption and I don't need quad core and 2.5 GbE WAN for now.
MT7981B based routers could be the natural dual core successor to E8450 or RT3200. But I see only GL-MT3000 currently supported and this device does not include an integrated switch and could be annoying under load with the active fan based cooling.
