In 2.6.3-rc2 all was OK. Don't know exactly about plain -rc3. In current BK, lazy umount is not working sometimes. udev start script mounts tmpfs on /dev and stop script does umount -l /dev. This doesn't return failure but nothing happens, /dev remain mounted and I can't start udev again. Doing umount -l /dev by hand again finally umounts it and udev can be started again. Plain umount /dev of course doesn't work because /dev is busy. This behaviour is 100% reproducible. Since 2.6.9-rc2 was OK, I guess this is a bug in current BK? -- Meelis Roos (mroos@linux.ee) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
