Description Need Real Name 2001-01-02 23:01:34 UTC

I am having troubles with VIA Rhine driver and my DLink DFE-530TX NIC: it 
works only after warm reboot from Windows 98. If booting linux first, 
driver displays correct card, IRQ and mem address info but does not 
function. The second part of issue is that driver does not support IRQ 
sharing and I had to manually distribute IRQs among the PCI slots.

I have a bug that is similar that the one you have. My ethernet card and my 
scsi card can't have the same IRQ. I had to manually distribute IRQs among the 
PCI slots. It seems that this kernel doesn't support IRQ sharing, because with 
the same configuration with Red hat 7 (kernel 2.2) it work properly.
it is very strange.

sorry my kernel with the problem was 2.4 in red hat 7.1
thank you

Comment 3 Arjan van de Ven 2001-05-09 18:05:29 UTC

lacassej: the 2.4 kernel is supposed to share IRQ's just fine.
What exact hardware is this ?
