Description of problem:
My ethernet card and my scsi card can't have the same IRQ. I had to
manually distribute IRQs among the PCI slots to be sure that the two card
have a different IRQ. It seems that this kernel (2.4) doesn't support IRQ
sharing, because with the same configuration with Red hat 7 (kernel 2.2)
it work properly.
I'am not sure but, if someone have an idea about my trouble please send my
Steps to Reproduce:
1.have the same IRQ for a ethernet card and a scsi card
2.try with ifconfig to bring up the ethernet adaptor
4.manually give different IRQ
5.and after that the two adaptor will work properly
Actual Results: the os will tell you: resource busy
and you cannot use yours ethernet card
Manually give different IRQ
and after that the two adaptor will work properly
I forgot my scsi card is adaptec 2920
and my ethernet card is a 82559ER
I try with other scsi card and the bug don't reappear.
Can you attach the output of "lspci -v" so we know exactly which devices we're
talking about ?

this is the lspci - v that you ask to me
Could you please send it as ascii not as kword ?

This is the file in an ascii file
Known problem with the fdomain driver. Unfortunately its an ancient card that we
don't really have enough information about.
Doug - if you can ping Justin Gibbs/Adaptec and get me the 'how to test for the
IRQ source being this card' instructions then I can fix this driver
Was finally fixed in mid 2.4
