Hello,
I think I catched aufs kernel oops, my first one ever :)
I'm running root aufs filesystem (aufs is /).
I start KDE, then I start console and execute remount to add a new
branch to union:
mount -o remount,add:1:/mnt/live/memory/images/some_dir
Then I start kbuildsycoca to refresh KDE menu.
Sometimes it is OK but after adding few branches this way dmesg shows
the error attached, after kbuildsycoca.
my configuration:
CONFIG_AUFS=m
CONFIG_AUFS_FAKE_DM=y
CONFIG_AUFS_BRANCH_MAX_1023=y
CONFIG_AUFS_SYSAUFS=y
CONFIG_AUFS_KSIZE_PATCH=y
there is approximately 10 branches in union.
