[Techtalk] Second try before reinstall--Kernel Oops

A very empathetic thank you to Telsa and Alan!

Thanks, will do.  That's probably the biggest piece of info I was
looking for, since it did look to me that the kernel wasn't playing
nice.  Naughty new fedora kernels!

I'll look into picking up a serial then unless the Fedora crew is going
to be turning out a 2.6 kernel release soon...one can hope, can't one?!

Yep, I get all that, I'm pretty intimate with the pda-related modules
from setting up both a Palm and more recently the Clie.

I figured that wasn't a Good Thing.

Yep, that's my zip drive which likes all the attention.

Well, not *quite* since I was still happily surfing the 'net and
collecting email.  ;-)

So the followup question, is there any way to recover from that crash
without rebooting?

I *was* using CUPS in Shrike before I did the clean install.  :-( 
Apparently that was no protection.  And I tried running the gui
configuration tool and it wouldn't accept any changes!  Strange. 
Anyway, I did a clean install of Shrike, then an upgrade to Yarrow,
still getting the kernel crashes but I can print now.  As soon as I get
the uncrippled xmms installed I'll check my volume applet.

Oh well, it can't go well for me all the time I guess.  My big success 
yesterday was getting my new AirPort card functioning in my iBook
running Yellow Dog.  Now I can surf from the couch, and setup was easier
and quicker in YDL than in Panther.

thanks again,
Beth
