btcreate / btextract hangs when booting from tape

Hi folks,

I have the following problem:

When I boot from a tape, created wit btcreate, with the command 'boot -fl
"nc" MKA500' the system will read in the bootblock and vmunix, but then
hangs forever after showing it will work in lazy swap mode. Obviously it
does not want to start btextract.

This occurs on different system types. In the past (Tru64 Unix 4.0D patch 3)
I could use this procedure successfully, but since I installed Patchkit 6,
it does not work any more. I tried to use the old btcreate/btextract/mktape
combination which worked for me before, but that did not work as well. It
seems some AdvFs patches interfere with btcreate/btextract. Luckily I can
boot from CD, skip the first 2 files, and then vrestore the saved files by
hand, so I don't have to fear I cannot restore the system. But I'd like to
have the nice boot-facility back for my +100 systems backed up in this way.

I have seen this problem mentioned before, but did not read any
solution/bypass.

Data:

O/S Tru64Unix 4.0D Patch 6,

System Disk: Root and /usr are both AdvFs with enough free space:

Filesystem 1024-blocks Used Available Capacity
Mounted on
root_domain#root 131072 56906 68336 46% /
/proc 0 0
0 100% /proc
usr_domain#usr 716800 513381 180808 74%
/usr

Can somebody shed me some light?
