Hi all, Having a small issue with aufs branch 3.10.x on linux 3.10.27. Compiles OK but when trying to boot "debian live", I see a kernel BUG when trying to mount aufs with a squashfs+tmpfs: --- BUG: unable to handle kernel NULL pointer dereference at 0000000000000018 IP: [<ffffffffa00d66bf>] au_test_loopback_overlap+0x34/0x59 [aufs] PGD 7736067 PUD 774e067 PMD 0 Oops: 0000 [#1] SMP Modules linked in: squashfs loop(0) aufs nls_utf8 isofs sg sr_mod cdrom ata_gen eric floppy 8139too ata_piix libata scsi_mod 8139cp mii [...] Call Trace: [<ffffffffa00bf527>] ? au_br_add+0x309/0x7ba [aufs] [<ffffffffa00c41a7>] ? vfsub_kern_path+0x29/0x2f [aufs] [<ffffffffa00c3319>] ? au_opts_parse+0x7bd/0x8096 [aufs] [<ffffffffa00c1d64>] ? au_opt_br+0x47/0x95 [aufs] [<ffffffffa00c2242>] ? au_opts_mount+0x82/0x1d5 [aufs] [<ffffffffa00bdb68>] ? aufs_fill_super+0x1cc/0x264 [aufs] [...]
--- "Debian live" tries to do something like that, with /cow being a tmpfs and /filesystem.squashfs a mounted loop squashfs. mount -t aufs -o noatime,noxino,dirs=/cow=rw:/filesystem.squashfs=rr aufs /root Is this a known issue? If so how can I resolve it? I can provide more information if needed. Thanks in advance, -- François
