(erhard_f@mailbox.org) --- (In reply to Christophe Leroy from comment #4) > Can you apply https://patchwork.ozlabs.org/patch/1213028/ and select > CONFIG_KASAN_VMALLOC Re-tried with 5.5-rc2 your KASAN_VMALLOC patch and this patch (https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/= ?id=3D7de7de7ca0ae0fc70515ee3154af33af75edae2c) to make -rc2 boot again. Result with KASAN is the same as before. If I enable CONFIG_KASAN_VMALLOC additionally the KASAN hit is gone. modprobing and removing btrfs shows no error then. Interesting! Double-checked it just to be sure. --=20 You are receiving this mail because: You are watching someone on the CC list of the bug.=
