hi folks,
I'm running a 2.6.16.16 kernel on a small Via Epia Nano N 10000E board
with a "Luke" processor.
Running a bridge over one on-board ethernet interface (via-rhine) and a
USB-to-ethernet adaptor D-Link DUB-E100 (with asix AX88772 chip, drivers:
usbnet + asix), I occasionally get an oops like the one I append to this
mail.
the adaptor is running in high-speed mode under high load (about 65..75
Mbps, full-duplex). the last occurrence of this error was when the board
had been running all night long, and then I logged in.
since the first messages in the Oops are about ehci_hcd (scan_periodic
and ehci_work), I chose this mailing list to present the error to. any
help would be warmly welcome.
greetings from
elmar
PS: I'll give you more info about the system, just as you need it.
