"Waiting for index to be ready (905 0)"

Question

The behavior of TM (and also Time Capsule) seems to have deteriorated significantly since I did the latest TC firmware upgrade. I realize this is the TM forum and that is the basis of this question, but the revised TC is much more difficult to be seen by the TM process since the upgrade and thus results in many failed or unfinished TM backups.
TM has failed in the last three attempts and seems to have fallen into a loop. The log of the atempt before the current one shows the following:
Starting standard backup

.... at which point, I guess the sleep timer kicked in.
The current backup attempt has the same initial messages and is presently looping on "Waiting for index to be ready (905>0)".
Any help and advice much appreciated.

When you say "disk problems", do you mean hardware problems, firmware problems or software problems?
On directly-attached disks, we see this when the disk spins down, but won't spin back up fast enough or properly; or with a USB disk that gets its power from the Mac, but not quite enough sometimes; or port or cable problems; or one that's beginning to fail. It's very hard to tell, of course, which.
I'm not very familiar with TCs, but a disk is a disk!
