"mount /mnt/removable" hangs. I have this line in fstab: /dev/sdb1 /mnt/removable auto defaults,user,noauto 0 0 If I do: mount -t vfat /dev/sdb1 /mnt/removable , it works ok.

works for me ... try running your `mount` through strace # umount /mnt/games/ # grep /mnt/games /etc/fstab /dev/hda3 /mnt/games auto defaults,ro,user 0 0 # mount -v /mnt/games mount: you didn't specify a filesystem type for /dev/hda3 I will try type vfat /dev/hda3 on /mnt/games type vfat (ro,noexec,nosuid,nodev)

Then I have to kill -9 it.
I have the same problem on amd64. I think it is related to a USB device. Workaround: add =sys-fs/e2fsprogs-1.40 to /etc/portage/package.mask and do: emerge -uD --deep world [ebuild UD] sys-libs/com_err-1.40_pre20070411 [1.40] USE="nls" 0 kB [ebuild UD] sys-libs/ss-1.40_pre20070411 [1.40] USE="nls" 0 kB [ebuild UD] sys-fs/e2fsprogs-1.40_pre20070411 [1.40] USE="nls -static" 0 kB ... at it works.
It has been fixed in linux kernel 2.6.22
