Description Jeremie Lacasse 2001-05-09 14:10:13 EDT
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows 98)

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 
a mail.
thank you 

How reproducible:

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

Additional info:

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 ?

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
Comment 7 Alan Cox 2003-06-06 08:26:02 EDT
Was finally fixed in mid 2.4
