Hi!

I have a 712 workstation at home and try to make it a diskless debian 
station.

I have other diskless machines where I do swap over nbd without problem 
(debian 2.6.15). I tried the same on the hp, but accessing /dev/nb0 
results in a crash.

I tried to have nbd in module or not, but this does not change anything.

I do not have the skills to go any further but do a bug report. If you 
need more informations just ask, I'd be glad to provide them.

Thanks in advance for any help.

Best regards,

     -- Vincent Stehlé
