More experience with USB lockups here.
I have an Apollo Pro (694x) and an Apollo Super South (686b),
and it's interesting how quickly this machine freezes under 2.4.18-pre1.
All I have to do is send about 100KiB/second over my NIC and the USB
(moving the mouse and tapping on the keys on my USB HID devices causes
a hard lock with no messages of any kind. Can't even get a serial
console.)
Tried with UHCI and JE driver. JE doesn't recognize the USB controller
half the time. It seems to me that this is similar to the problem
with a saturated PCI bus that someone posted a latency fix for.
I'd appreciate any input. A similar machine does this on windows as
well, too. BIOS is as late as it gets.
