lhype booting debootstrapped debian image over nfsroot, partial success

[bert hubert <bert.hubert@netherlabs.nl>]

Hi!

Bored by previous lhype success, I tried to boot a debootstrapped debian
over nfsroot, and lo, this almost works!

Commandline:
# drivers/lhype/lhype_add 256m 0 ./vmlinux --tunnet=192.168.1.20
 root=/dev/root nfsroot=/home/ahu/lhype-root
ip=192.168.1.21:192.168.1.20:192.168.1.20

This with lhype.patch current as of this message and 2.9.20-rc4.

The boot process stops after:
Starting periodic command scheduler: crond.

Trying to use the console yields:
lhype_add: Failed to get DMA buffer from (nil): No such file or directory
lhype_add: console: no dma buffer!: No such file or directory

/dev/tty does exist on the root: crw-rw-rw- 1 root tty 5, 0 Jan  7  2007 /dev/tty

However, TCP/IP was working, so I installed an ssh server so I could log in
over the network, but no dice:
Starting OpenBSD Secure Shell server: sshdPRNG is not seeded
 
Installing telnet, and removing /etc/securetty allowed me to login as root,
but this doesn't always work. When I try to, lhype prints out the following,
if it works or not:

lhype_add: Failed to get DMA buffer from 0xb7fff008: No such file or directory
lhype_add: network: no dma buffer!: No such file or directory
lhype_add: Failed to get DMA buffer from 0xb7fff008: No such file or directory
lhype_add: network: no dma buffer!: No such file or directory
(8 more of these 2)
lhype_add: Pending dma 0x7906c0, addr 0xb7fff000

When it does work, things sort of work, but it looks like timing is
seriously off:

intel:~# uptime
 01:52:22 up -24855 days, -3:-14,  1 user,  load average: nan, nan, 0.03

The clock appears to run around 5 times too slow.

But things are looking pretty nice! Booting from nfsroot beats a fixed image
any day for me.

Keep up the good work!
