I installed ueagle-atm, which, by itself, is working fine with an

The problem I have, is that when I copy a file from a DVD to harddisk,
the internet connection almost dies (it slows down terribly, so much so
that established connections actually disconnect, ping looses packets,
DNS lookup fails, etc). After copy ends, all returns to normal.
The machine is an AMD64, still in x86 mode though. CPU activity is very
low during the copy, so it's not a CPU problem. Kernel is 2.6.20.2. APIC
is enabled. No error message found in either /var/log/messages or syslog.
DVD and HD are on different IDE interfaces.
Can anyone suggest where to start looking for a solution?

It pretty much has to be an IRQ sharing issue,
most likely in the USB driver side of the house.
Oh, wait a minute.. that's not the correct IRQ, is it?
Your ueagle-atm must be on this one:
20: 90833792 3057782 IO-APIC-fasteoi ohci_hcd:usb1
In which case, it's not likely to be an interrupt sharing issue.
Can you confirm this?
Also, try moving your ueagle-atm to one of the ehci usb ports
and see how that affects things.
