Hello! I'd like to ask if I can go on with my lguest to-do list or if PAE is causing any problems (if this is the case, please let me know and I'll try to fix it). regards Matias
Hello I'm trying to use lguest in order to use it in nfsroot.
Host: linux, sharing /mnt/nfs
Guest: lguest, mounting inside the initramfs /mnt/nfs and booting on it. My logs are full of
lguest: network: no dma buffer!: Resource temporarily unavailable
as you can see here:
INIT: version 2.86 booting
lguest: network: no dma buffer!: Resource temporarily unavailable
lguest: network: no dma buffer!: Resource temporarily unavailable
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
lguest: network: no dma buffer!: Resource temporarily unavailable
lguest: network: no dma buffer!: Resource temporarily unavailable
lguest: network: no dma buffer!: Resource temporarily unavailable
lguest: network: no dma buffer!: Resource temporarily unavailable
And so on.
I run the 2.6.26 linux kernel.
I can reproduce it by downloading large amount of data:
root <at> darkst
ar:~# scp -P 822 octane-Q0ErXNX1Ruag8F5M4K59mw@public.gmane.org:/var/samba/iso/slackware-12.1-install-d1.iso /dev/null
octane-Q0ErXNX1Ruag8F5M4K59mw@public.gmane.org's password:
slackware-12.1-install-d1.iso 5% 35MB 1.0MB/s 10:11 ETAlguest: network: no dma buffer!: Resource temporarily unavailable
lguest: network: no dma buffer!: Resource temporarily unavailable
slackware-12.1-install-d1.iso 5% 36MB 1.0MB/s 10:09 ETAlguest: network: no dma buffer!: Resource temporarily unavailable
lguest: network: no dma buffer!: Resource temporarily unavailable
Do you have an idea how to solve this?
Thanks
