Pure trial and error in the first time. When realising that something is
wrong with the assigned interrupts (looking at the kernel output) we
tried to set the ones that were working in a 2.4 kernel. When the
machine finally booted a "lspci" showed that the slot number changed.

lspci, sounds easy ;-)
but i never would have looked at slot numbering....

Is it that onboard network tulip kind of thingy? Do you have some other
PCI cards installed?

the card is onboard. since i had some issues with this card in early 2.4
kernels too, i used to have another NIC. in fact, very often i only
compiled with 3c59x enabled - OF cared about the onboard NIC (tulip) and
once the kernel is loaded, the tulip is not needed any more and 3c59x
takes over.

http://nerdbynature.de/bits/sheep/2.6.10-rc3/  has some details.

I used to have an extra symbios logic scsi-host-adapter installed.
On high network load and loading/writing to a HD (using onboard scsi), I
noticed a lot of problems: either the scsi-host-adapter lost the
interrupt or the network driver lost some packets or both. After having
removed the extra scsi-host-adapter it works fine now.

hm, when i had 3 scsi-disks in this machine (fine IBM ones, hmmmm..) i
only used the on-board scsi-bus. there was no other scsi-host-adapter
inside, but i noticed the very same problems: upon massive i/o, the
machine got stuck for 30sec, sometimes longer, load increased to 30..40 or
so, then the machine got back, with a syslog full of scsi errors.



it's still so incredible that a 3-liner solved this issue. the bug-report
was opened over a year ago...

thanks again,
Christian.
