I think that I have covered my bases, but I could be wrong.\n\nOn Debian 6.0.7 Squeeze with the native kernel version, I have compiled SPL and ZFS. This was my configure command for ZFS:\n\n```\n./configure --with-linux=/usr/src/linux-headers-2.6.32-5-common --with-linux-obj=/usr/src/linux-headers-2.6.32-5-amd64 --with-spl=/usr/src/spl-0.6.0-rc12/2.6.32-5-amd64/\n```\n\nWhen I installed the .deb files produced by \"make deb\", dpkg gave this warning:\n\n```\nWARNING: /lib/modules/2.6.32-5-amd64/addon/zfs/zfs/zfs.ko needs unknown symbol__taskq_destroy\nWARNING: /lib/modules/2.6.32-5-amd64/addon/zfs/zfs/zfs.ko needs unknown symbol__taskq_member\nWARNING: /lib/modules/2.6.32-5-amd64/addon/zfs/zfs/zfs.ko needs unknown symbol__taskq_dispatch_ent\nWARNING: /lib/modules/2.6.32-5-amd64/addon/zfs/zfs/zfs.ko needs unknown symbol__taskq_create\nWARNING: /lib/modules/2.6.32-5-amd64/addon/zfs/zfs/zfs.ko needs unknown symbol__taskq_wait\nWARNING: /lib/modules/2.6.32-5-amd64/addon/zfs/zfs/zfs.ko needs unknown symbol__taskq_init_ent\nWARNING: /lib/modules/2.6.32-5-amd64/addon/zfs/zfs/zfs.ko needs unknown symbol__taskq_dispatch\n```\n\nTrying to load the module with \"modprobe zfs\" gives:\n\n```\nFATAL: Error inserting zfs (/lib/modules/2.6.32-5-amd64/addon/zfs/zfs/zfs.ko): Unknown symbol in module, or unknown parameter (see dmesg)\n```\n\n\"dmesg\" lists message, preceded by many other similar ones about different symbols:\n\n```\n[ 1066.496068] zfs: disagrees about version of symbol vn_fsync\n[ 1066.496069] zfs: Unknown symbol vn_fsync\n```\n\nCan anyone give me any pointers? Have I incorrectly specified my kernel headers?

I got my zfs pool back up and running."}}
