more hints

If I remove "device pmtimer" from my config, I get a consistent panic,
or variation of:

Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0x0
fault code              = supervisor read, page not present
instruction pointer     = 0x8:0xc0135b0a7
stack pointer           = 0x10:0xd68f2c48
frame pointer           = 0x10:0xd68f2c64
code  segment           = base 0x0 limit 0xffff, type 0x1b
processor eflags        = interrupt enabled, resume, IOPL=0
current process         = 12 (swi7: tty:sio clock)
trap number             = 12
panic page fault

...


This is with leaving my USB 2.0 drive turned on during boot time.  If
I use the same kernel (sans pmtimer) , but boot with my USB drive turned
off, all is well.  Or, I can put pmtimer back in the kernel and boot
with the drive turned on, but sooner or later I'll get some type of
panic.  Some kind of timimg issue?.

I think all of these panics have something to do with leaving the USB
drive on at boot time.  It seems like I don't have any issues if it
stays turned off.  That's probably why we're not seeing any reports, I
doubt a lot of folks are using a USB 2.0 HD along with ehci...

Again, all this started shortly after July 14th.  The USB DMA changes
may have something to do with this...
