The recent changes to the usb-ohci.c driver in 2.4.4-pre5 seem to be
causing serious problems on my G4 Cube powermac. I haven't tracked
down exactly what the problem is, but the symptom is that I get an
OHCI unrecoverable error; using the USB speakers seems to trigger this
very quickly.
The USB controller is the integrated one in the Apple "Core99"
chipset. The relevant bit from /proc/pci is:
Bus 1, device 24, function 0:
USB Controller: Apple Computer Inc. KeyLargo USB (rev 0).
IRQ 27.
Master Capable. Latency=16. Min Gnt=3.Max Lat=86.
Non-prefetchable 32 bit memory at 0x80082000 [0x80082fff].
Has anyone else seen this? It works OK with the Lucent USB chip on my
1999 G3 powerbook.
Paul.
