[mythtv-users] Network Device Failure.....

[John Nelson]

Mr. Wood,

Well, I ran both lspci and the cat /proc/interrupts commands and the 
outputs are copied below.  I was thinking a USB ethernet adapter would 
be a bad idea.  As for PCMCIA, I have the ability to get an IDE adapter 
that goes into a 5.25 slot on a case.  I have no idea about its specs, 
if Linux wil leven see it, etc.  Plus, this would be a very certain kludge.

The First cut/paste is the thernet type.  The second is the interrupts.

I do notice there are quit a few on the 10: 499501 row.  Being a bit of 
a wet behind the ears Linux newbie, is the 10 or the 499501 the 
interrupt?  Or both?  The fact that there is one of my capture cards, 
two USB ports and my Ethernet on whatever that row, do you think that 
might be part of the problem?

As for whether my network device support is modular or compiled in, I 
will have to look into that.

Thank you for the help.  Looks like I will be learning more about 
modular versus compiled in support as well as Interrupt handling in 
Linux.  :-)   (And while new, I do know a bit of generalized stuff ....)

Sincerely,
John Nelson
