Last modified: 2007-04-18 12:33:09 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: Always 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 ?
Created attachment 17927 [details] this is the lspci - v that you ask to me
Could you please send it as ascii not as kword ?
Created attachment 17986 [details] 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
