>Description:
On my Toshiba Laptop (Libretto L5), cardbus socket is disable at boot (is in D3 power state). cbb(4) driver can't initialize correctly the socket:
cbb0 at pci0 dev 18 function 0: Toshiba ToPIC100 PCI-CardBus Bridge (rev. 0x33)
cbb0: bad Vcc request. sock_ctrl 0xffffff88, sock_status 0xffffffff
cbb0: disabling socket
new status 0xffffffff
cbb0: cacheline 0x0 lattimer 0x40
cbb0: bhlc 0x24000
cbb0: interrupting at irq 7
cardslot0 at cbb0 slot 0 flags 0
Socket is unusable (inserting a card does nothing).
>How-To-Repeat:
Boot a netbsd-current after merge of jmcneill-pm branch.
>Fix:
Changing power state before socket initialization:
