| |
Umount report "busy" when i try r/o remount the root filesystem at end of halt script. My halt script ends with:
# Begin of halt kill -9 -1 umount -a mount -n -o remount,ro / halt # End of halt
Umount (and mount on next line too) report "/: device is busy" and the root filesystem stay not correctly unmounted. But when i press magic key "u" (emergency remount), the filesystem is correctly remounted. All other mounted filesystems are correctly unmounted by "umount -a". This bug is present only on my motherboard with SiS5513 chipset; on other motherboard with VIA chipset and the totaly same linux it's all right. The second thing is, that on kernels 2.2.X (up to 2.2.13, later i've not tested) it's ok too. The version of mount has not any influence.
