Hi,

When  I orginally  sent out the my first email  on  this  I was  having 
irq conflicts and  waas  hoping  to resolve them.  I  was asked to 
update the bios to  the latest version, I did. It had no effect.  The 
errors were:
Interrupt storm detected on "irq10: pcic1"; throttling  interrupt source 
and
Interrupt storm detected on "irq11: pcic0 uhci0"; throttling  interrupt 
source
 I was asked to post dmesg and a copy of my kernel , I did. It is nice 
to see the thread continue however it has lost me. So I would like to 
ask again. How do I resolve the  interrupt storm  issues so they aren't  
there anymore when  I boot up? The problem didn't exist in  4.x   for 
me.  Can I  run 5.x without  them or am I better off staying  with 4.x 
for a while longer ?  If I actually have  my pcmcia card installed  on 
boot up it will cause  the boot up to freeze at the " Inital i386 
initialization" part of the  boot up.

Sincerely,
Brendhan
