2010-05-13 Thread Christoph Egger
Hi! Attached patch corrects use of PMAP_CANFAIL to not be or'd with protection. Pass protection to the protection parameter of pmap_enter instead. Any comments? Christoph diff -r f0002006fa5e sys/arch/xen/xen/privcmd.c --- a/sys/arch/xen/xen/privcmd.cThu May 13 17:30:37 2010 +0200 +++

I have an HP SCSI scanner that works. I have had problems with USB scanners that seem similar to yours but not yet figured them out. My next step is to disable usscanner. pgpupaCnj0Qbq.pgp Description: PGP signature

Debugging via firewire is a much better bet.. It should only take a few hours to make the necessary adjustments to libkvm and the driver. Nobody has stepped up to the plate yet though. On Thu, May 13, 2010 at 08:26:10AM -0400, Greg Troxel wrote: > > The comment was made when I proposed that
