wi(4)/mini-PCI senao / not always initialized on boot.

[Dirk-Willem van Gulik]

With a mini-PCI formfactor wi(4) card (Senao) I am seeing

	wi0: <Intersil Prism2.5> mem 0xa0000000-0xa0000fff irq 10 at device 16.0 on pci0
	wi0: CSR_READ_2(WI_HFA384X_SWSUPPORT0_OFF) wanted 18989, got 65535
	device_probe_and_attach: wi0 attach returned 6

on roughly 4 out of very 5 reboots. A few extra reboot/powercycles seems
to get me past it. Long/short/cold/warm resets or reboots seem not to
clearly affect when one gets through successfully.

I already tried adding some of the COR reset code (bit 7) to the native
PCI branch in wi_pci_attach() but to no avail sofar.

Any suggestion as to what this might be - and/or where I should look ?

Thanks,

Dw
