The second bisection (from v6.15-rc6 to next-20250512) is finished now:

This commit leads to lockups and kernel panics after
watching ~5-10min of a youtube video while compiling a kernel,
reverting it in next-20250512 is possible:
76a853f86c97 ("wifi: free SKBTX_WIFI_STATUS skb tx_flags flag")
This commit leads to the boot failure, reverting leads to the
compile error it is supposed to fix:
97f4b999e0c8 ("genirq: Use scoped_guard() to shut clang up")

So are these kernel bugs or a clang bugs?
