kernel .config (6.1-rc6, PowerMac G4 DP)
Somehow I had a hard time reproducing this...
Finally it turned out that this is not 100% deterministic. I'll attach my new
-rc6 .config which provokes the early boot failure best.
The same kernel can run into this early boot issue, or it can fail boot later
with "BUG: KASAN: slab-out-of-bounds in filemap_map_pages+0x2c8/0x5d0" or it
can boot up just fine.
I had the impression the early boot issue is provoked easier when
CONFIG_DEBUG_PAGEALLOC_ENABLE_DEFAULT=y is set or debug_pagealloc=on is set as
boot parameter as you suggested. Also it seems to be provoked easier when
CONFIG_NETCONSOLE=y is used and properly configured (perhaps also linked to my
yet-to-be-posted netconsole bug?).
