CentOS - May 2007 - CentOS 4.4 on Thinkpad T30

I installed CentOS 4.4 on an old T30 I had lying around using a  
slightly modified kickstart file that I use to install on desktop  
systems.  I had to manually fix the resolution for X, but everything  
appears to work fine out of the box otherwise.  Except for two issues:

   o After a period of inactivity (> 30 minutes), the laptop
     will go to sleep and I can not wake it up other than a
     hard reset/reboot.
   o If I pull the network cable, almost every command hangs
     (this is with a local account, although the system is
     configured for NIS); if I reconnect the network, the
     hanging commands complete (I've tried running strace,
     but that hangs as well).

I think the second issue also happens on my desktop systems, so it's  
not related to the laptop itself, but it is more likely that a laptop  
be used off the network.

Any suggestions?

Regardless of whether the current account is local or not, most 
authorization routines will want access to the entire passwd and group 
databases.

You can try using nscd with obscenely long cache times, or you can 
make your machine an NIS slave server, or you can make all accounts 
local.
