CVS commit: src/sys/dev/usb

Module Name:    src
Committed By:   matt
Date:           Wed Dec 15 23:38:15 UTC 2010

Modified Files:
        src/sys/dev/usb: files.usb usb_mem.c

Log Message:
Add a workaround (hopefully temporary) for corrupted usb fragments on powerpc.
With this in effect, USB is now usable on some powerpc platforms again.
Basically this prevents the DMA portion of the fragment ever overlapping the
usb_frag_hdr which is enough to solve the problem.  To enable this, add


to your config file.
Switch from malloc to kmem.
