>Description:

The Cardbus Adapter in the Sony VAIO PCG-F807K gets a bad VCC request,
and is switched off:

  cbb0 at pci0 dev 12 function 0: vendor 0x1180 product 0x0478 (rev. 0x80)
  cbb1 at pci0 dev 12 function 1: vendor 0x1180 product 0x0478 (rev. 0x80)
! cbb0: bad Vcc request. sock_ctrl 0xf000ff00, sock_status 0xf000e2c3
! cbb0: disabling socket
  cbb0: cacheline 0x0 lattimer 0x10
  cbb0: bhlc 0x821000
  cbb0: secondary bus number uninitialized; try PCI_BUS_FIXUP
  cbb0: interrupting at irq 9
  cardslot0 at cbb0
  pcmcia0 at cardslot0
! cbb1: bad Vcc request. sock_ctrl 0xf000ff00, sock_status 0xf000e2c3
! cbb1: disabling socket
  cbb1: cacheline 0x0 lattimer 0x10
  cbb1: bhlc 0x821000
  cbb1: secondary bus number uninitialized; try PCI_BUS_FIXUP
  cbb1: interrupting at irq 9
  cardslot1 at cbb1
  pcmcia1 at cardslot1

The slots are completely inoperative after that - including PCMCIA
operation.

This used to work with NetBSD-4.0, NetBSD-4.0.1, NetBSD-4.0_STABLE as
of late January 2009 (and I think, with NetBSD-3).
