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
Interrupt storm detected on "irq10: pcic1"; throttling interrupt source
Interrupt storm detected on "irq11: pcic0 uhci0"; throttling interrupt
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.
