Are those NBD logs still happening frequently? I wouldn't say 128MB is enough, no. Not for things like Firefox / OOo, since they take their fair share (getting better though) of local X server RAM (which is on the client). Of course it should be plenty to get to an LDM login prompt, though. Have you tried updating your chroot to the latest packages? I apologize if you've said you did in an earlier post.. but if you haven't try looking here - it's fixed a few problems for me recently involving NBD_SWAP issues: http://lns.wikidot.com/ltspchrootfixsources - I would also like to know if that page contains any errors since I wrote it just last week.
