Hi,
I have Gutsy edubuntu server setup for about 10 thin clients. I was able to
boot with 3COM and Intel UNDI cards that have PXE facility, but network cards
such as VIA Rhine, Realtek gets the IP address, starts loading to the satge of
bringing up the ldm login screen and stop with a blinking cursor. Below is the
error response from one of them
[ 38. 900730] vt8623fb 0000:01:00.0: memory size detection failed (0,20),
suppose 16MB.
Has anyone experienced this and what is the way around this?
Thanks always!
David

I have four of these Dell GX50 model. Two work fine. Two report the
same code (different code numbers) and "hang" after these lines appear:
first machine:
[20.645497] PCI: Cannot allocate resource region 4 of device 0000:00:1f.2
[20.645590}PCI: Cannot allocate resource region 4 of device 0000:00:1f.1
second machine:
[20.727272] PCI: Cannot allocate resource region 4 of device 0000:00:1f.2
[20.727365] PCI: Cannot allocate resource region 4 of device 0000:00:1f.1
I am not sure if these are Dell error report (from GX50 computer) or
Ubuntu/LTSP report error. I have confirmed that the BIOS is set the
same on all machines. What could be wrong?

Hi JIm,
Thanks for the tip... I followed your advice but I am still getting these
long delays.
It even happened to one of my local users the other day. The problem
cleared itself when I deleted that user's profile directory & it was
rebuilt using the defaults on login.
This might be a clue but I have no idea what's going on still, and users
have to log off with CTRL-ALT-BACKSPACE if they don't feel like waiting up
to two minutes for the Quit dialogue to come up.
Any other ideas out there??
Regards,
Tom Wolfe

Hi Daniel, thanks for the ideas.
That was a misspelling (I typed it in, not cut & paste)
I swtiched to using sysctl.conf after reading that the
/etc/network/options is deprecated
Still the same problem.
I've resorted to a cron job that sets it to 1 ever minute.... quite a hack
so I'd love to know the real cause of the problem.
NOte that I didn't do a standard Edubuntu install, I had Edubuntu
workstation, and then installed LTSP, etc. on top of it. I imagine I have
a config missing somewhere.
Regards,
Tom Wolfe

This seems to be a bug in ubuntu/edubuntu 7.10. On my ubuntu 7.1 pc i
get this problem often after logging out and in again at once. I wrote a
bugreport at https://bugs.launchpad.net/ubuntu/+bug/153180 but did not
worked on the problem any longer, because i don't log out and in so
often. I also can't reproduce the problem if i want to. But it is still
there.
I think your problem is the same and is not special to edubuntu.

performance in a vmware hosts.
