Subject: Conflict between ide and usb?
Hi all.
I installed ueagle-atm, which, by itself, is working fine with an
MT-810 modem.
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?
Cheers,
John
