(erhard_f@mailbox.org) --- Created attachment 303254 --> https://bugzilla.kernel.org/attachment.cgi?id=3D303254&action=3Dedit 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 n= ew -rc6 .config which provokes the early boot failure best. The same kernel can run into this early boot issue, or it can fail boot lat= er 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=3Dy is set or debug_pagealloc=3Don is= set as boot parameter as you suggested. Also it seems to be provoked easier when CONFIG_NETCONSOLE=3Dy is used and properly configured (perhaps also linked = to my yet-to-be-posted netconsole bug?). --=20 You may reply to this email to add a comment.
