(erhard_f@mailbox.org) --- Found out this is probably a cause for bug #205283. For doing some btrfs te= sts with 5.5-rc1 kernel I needed to disable KASAN in lib/raid6/Makefile (KASAN_SANITIZE :=3D n) as btrfs pulls in raid6_pq. btrfs gets modprobed seemingly ok the 1st time, but removing and reloading = it provokes bug #205283. # modprobe -v btrfs # modprobe -r -v btrfs rmmod btrfs rmmod zlib_inflate rmmod libcrc32c rmmod raid6_pq rmmod zlib_deflate rmmod lzo_decompress rmmod lzo_compress rmmod zstd_compress rmmod zstd_decompress rmmod xor # modprobe -v btrfs insmod /lib/modules/5.5.0-rc1-PowerMacG4+/kernel/lib/zlib_inflate/zlib_inflate.ko= =20 insmod /lib/modules/5.5.0-rc1-PowerMacG4+/kernel/lib/libcrc32c.ko=20 insmod /lib/modules/5.5.0-rc1-PowerMacG4+/kernel/lib/raid6/raid6_pq.ko=20 insmod /lib/modules/5.5.0-rc1-PowerMacG4+/kernel/lib/zlib_deflate/zlib_deflate.ko= =20 insmod /lib/modules/5.5.0-rc1-PowerMacG4+/kernel/lib/lzo/lzo_decompress.ko= =20 insmod /lib/modules/5.5.0-rc1-PowerMacG4+/kernel/lib/lzo/lzo_compress.ko=20 insmod /lib/modules/5.5.0-rc1-PowerMacG4+/kernel/lib/zstd/zstd_compress.ko= =20 insmod /lib/modules/5.5.0-rc1-PowerMacG4+/kernel/lib/zstd/zstd_decompress.k= o=20 insmod /lib/modules/5.5.0-rc1-PowerMacG4+/kernel/crypto/xor.ko=20 insmod /lib/modules/5.5.0-rc1-PowerMacG4+/kernel/fs/btrfs/btrfs.ko --=20 You are receiving this mail because: You are watching the assignee of the bug.=
