On the 2 affected boxes, 2.6.36-rc6-git6 - one had no problems and and one several rebuilds and reinstalls of modules had to be done to get it to work with the exception of one module. slipstream:/home/lancelot # depmod -ae -F /boot/System.map WARNING: Can't read module /lib/modules/2.6.38-rc6-git6-smp/kernel/drivers/mtd/nftl.ko: Not a directory Listing the module it says 0 bytes whereas before the reboot it was OK. slipstream:/home/lancelot # l /lib/modules/2.6.38-rc6-git6-smp/kernel/drivers/mtd/nftl.ko -rw-r--r-- 1 root root 0 Feb 26 22:33 /lib/modules/2.6.38-rc6-git6-smp/kernel/drivers/mtd/nftl.ko # rpm -qa|grep xfsprogs xfsprogs-3.1.4-1.3.x86_64 slipstream:/home/lancelot # df -T Filesystem Type 1K-blocks Used Available Use% Mounted on rootfs rootfs 903211908 615966196 287245712 69% / devtmpfs devtmpfs 4056088 1024 4055064 1% /dev tmpfs tmpfs 4096140 14928 4081212 1% /dev/shm /dev/sda2 xfs 903211908 615966196 287245712 69% / none tmpfs 4096140 0 4096140 0% /lib/bootchart/tmpfs /dev/sda1 reiserfs 52426492 854848 51571644 2% /boot /dev/sdb1 reiserfs 302735588 263377460 39358128 87% /home/lancelot/ftp none tmpfs 4096140 252 4095888 1% /tmp none tmpfs 4096140 0 4096140 0% /lib/bootchart/tmpfs tindog:~ # df -T Filesystem Type 1K-blocks Used Available Use% Mounted on rootfs rootfs 912135984 386160972 525975012 43% / devtmpfs devtmpfs 1990668 316 1990352 1% /dev tmpfs tmpfs 2029860 4476 2025384 1% /dev/shm /dev/sda1 xfs 912135984 386160972 525975012 43% / none tmpfs 2029860 0 2029860 0% /lib/bootchart/tmpfs /dev/sdb1 btrfs 419931036 47466788 362246284 12% /data1 none tmpfs 2029860 568 2029292 1% /tmp none tmpfs 2029860 0 2029860 0% /lib/bootchart/tmpfs Regards Sid.
