Probably solved with http://www.netbsd.org/~matt/uvm_km.txt.
Needs testing.

This point was fixed yesterday, just in time!

Example: This is a typical panic without USB_FRAG_DMA_WORKAROUND, when
plugging in an USB device:
  trap: kernel read DSI trap @ 0xb6938101 by usb_allocmem+0xec: srr1=0x9032,
  r1=0xaa759cc0 cr=0x28000088 xer=0 ctr=0x4199ac dsisr=0x40000000
  save LR(0xfffffffd) is inavalid.


Two more, which I forgot:

- (since ~5.99.40 or earlier?) Random lock errors, when launching a kernel.
  With some kernel revisions this happens frequently, with others rarely.
  The workaround is to boot the kernel once again, until it works.
  Example (messages appear before the copyright):
  WARNING: add memory segment 10000000-20000000,
  WARNING: which was not recognized by the Firmware.
  Reader / writer lock error: rw_vector_enter: lock against myself
  lock address: 0x0000000000459744
  current cpu:                   0
  current int:  0x000000000043c740
  owner/count:  0x000000000043c740  Flags: 0x0000000000000004
  panic: lock error

- (5.99.59) vr0: device timeout. Problems with vr(4). Might be 5.99.59 only.
  Needs more testing.
