GCC 13.2 and > older from crosstool work just fine. I had held off moving to 14.1 due to Kalle's issue as well as one other internally-reported issue, but since a few others said they didn't have issues, I thought I'd try it out for my laptop build in case it is just a NUC-related issue. And what I'm seeing after reboot and selecting the new image from GRUB is: Loading Linux 6.10-rc6-wt-ath+ ... Loading initial ramdisk ... and that's it. It sits there with that on the display. We tend to enable a lot of debug config options, so I'm wondering if one of them is contributing to the issue? Guess I'll turn off a bunch of those options and try again. /jeff
