Re: Pegasos2 hangs during usb_discover()

Some more information on this problem. Maybe somebody has an idea:

The Pegasos enters an infinite loop in usb_allocmem() due to a corrupted
usb_frag_freelist entry, which was just allocated in the previous call.

Probably caused by a USB DMA transfer, the block, offs and next fields of
the head usb_frag_dma node are trashed. This is an uhci controller.

Is it possible to do USB transfers without DMA for testing? I see not many
possibilities to debug it further.

USB worked some months ago. No other PPC port seems to be affected. Are
other ofppc (non-Pegasos) machines affected? Any information is welcome.
