Ahem.

You /may/ want to remind me, next time, that umounting all filesystems 
except root, remounting root read-only, AND raid-stop'ing all arrays 
would be a good idea before doing this ( I forgot the last one )

Also, it seems that all drives de-allocate a sector every time I do this, 
and this is costing my system integrity...


Yes, it happens on all drives on the controller, and I've 2:
IBM 60GXP, 40GB == /dev/hde
Quantum LM15, 15GB == /dev/hdg

booting into multiuser command-line mode, no X, login as root, umount 
everything, "smartctl -a /dev/hde" ( or hdg ) gets 2 information lines, 
the second being the model# of the drive, and it never reaches the third 
line ( the newline doesn't appear ), and the drive-light comes on, and 
it's permanently hanged.

I'd thought this would be implicit in the 
* "cat /proc/ide/hde/identify" gets the same results *
comment I'd made previously, but did it out of curiosity...


When I did it on the Quantum, the Quantum's drive-light came on ( it's in 
a "mobile-rack" ), so it seems that the drive-light actually is still 
connected to the drive at that point, though nothing useful goes on 
after...


By the way, I seem to have hit this with the earlier 2.4.x kernels, ( 
IIRC ), but had /so/ much problems with flaky config and flaky distros 
at the time, that I didn't get that info out then ( by the time I got a 
stable system, I'd forgot, sorry... )


* Tell me which kernels you want me to try ( except ext3-broken ones ), 
and I'll do it, so you can scope where-the-break-is better, TIA *
