From: Magicloud Magiclouds on 28 Jun 2010 22:20 Hi, I am trying to make a debian sid system with btrfs as root. I installed debian sid on ext3 root, compiled 2.6.34 kernel. Booted to 2.6.34, it mounted a btrfs data partition right. Then I booted into debian live, converted the root to btrfs, rebooted. I got this: FATAL: Error inserting btrfs (/lib/modules/2.6.34/kernel/fs/btrfs/btrfs.ko): Unknown symbol in module, or unknown parameter (see dmesg) modprobe: FATAL: Error inserting btrfs (/lib/modules/2.6.34/kernel/fs/btrfs/btrfs.ko): Unknown symbol in module, or unknown parameter (see dmesg) Any idea? Thanks. -- 竹å¯å²å¦¨æµæ°´è¿ å±±é«åªé»éäºé£ -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?

I think there might be some related modules missing, but how to check? >> (/lib/modules/2.6.34/kernel/fs/btrfs/btrfs.ko): Unknown symbol in >> module, or unknown parameter (see dmesg) >> modprobe: FATAL: Error inserting btrfs >> (/lib/modules/2.6.34/kernel/fs/btrfs/btrfs.ko): Unknown symbol in >> module, or unknown parameter (see dmesg) >>  Any idea?
