Interesting it does not seems to be able to fetch the firmware
information of the card. As it would normally list something like:
wi0: <Intersil Prism2.5> mem 0xa0000000-0xa0000fff irq 10 at device 16.0 on=
pci0
wi0: [ITHREAD]
wi0: using RF:PRISM2.5 MAC:ISL3874A(Mini-PCI)
wi0: Intersil Firmware: Primary (1.1.1), Station (1.8.2)
wi0: Ethernet address: 00:02:6f:4a:cd:f5

Usually the firmware on the card is this biggest issue, causing the
card not getting detected, generating all the device timeout messages.
Running new firmware seems to fix it for a while. ```man 4 wi''' lists
the minimum required versions. Some firmware upgrade hints are listed
over here:

We had 200+ wi(4) cards running in our Wireless Metropolitan Network
and where running into the same walls as you did, every new release
issued more problems with those wi(4) cards. By the end we desired to
replace them all by ath(4) based cards (active development on the
driver :-)).
