What about the "device busy" umount2 problems? - With 2.3.99-pre6-3 I still
get several failed umount2s on shutdown or indeed when I try to do it
manually. [Rebooting into 2.3.49 all works fine, 2.3.99-pre5 was already
affected]
With Alexander Viro's patch from Fri, 14 Apr 2000 22:48:38 -0400 (EDT) I
still get the errors but now its on different mount points!?!
IIRC the last two times I was rebooting (post patch) both /root and / were
affected (i.e. device busy), both residing on the same SCSI channel, and
same UW hard disk for that matter.
Before the above patch I was getting things like /usr/local, /home & others
being busy. - However only ext2 file systems have been affected (in my
case) so far.
It might well be just all partitions I have written to? (but I am not sure
100% of write cases are affected) - see other mails from people about this
from before.
Correct me if I am wrong but, IMHO this problem belongs under the "In
Progress" heading since I believe Alexander Viro is working on this?
