Looking at the last part, "Error 139" was confirmed to be fixed in 6.18, 
right? At least reading [1] there I find

"it was issue of 6.18.0-rc6 kernel itself. After switching to default 
Arch Linux kernel build went without problem and I'm now on 6.18 stable 
kernel."

Did you mange to report the make issue you reported here [2] on 6.18 as 
well, or only pre 6.18-rc7?
