Hi all,
I've encountered a peculiar quirk in either this laptop or FreeBSD with
IPW2915ABG. For some reason or another, either the Thinkpad turns the
card on at bootup, or FreeBSD's if_iwi driver and acpi_ibm mistakenly
think the card is turned on.
My loaded modules:
Id Refs Address Size Name
1 14 0xc0400000 4033b4 kernel
2 1 0xc0804000 5e28 snd_ich.ko
3 2 0xc080a000 20448 sound.ko
4 1 0xc082b000 3f44 acpi_ibm.ko
5 17 0xc082f000 6057c acpi.ko
6 1 0xc0890000 41c4 wlan_tkip.ko
7 1 0xc0895000 6fe4 wlan_ccmp.ko
8 1 0xc1d7c000 18000 linux.ko
Notice that if_iwi is NOT loaded.
Let's have a look at dev.acpi_ibm.0.wlan
dev.acpi_ibm.0.wlan: 1
Well thats odd, why would acpi think the wireless chip is turned on with
no driver loaded?
Let's load if_iwi for kicks
iwi0: <Intel(R) PRO/Wireless 2915ABG> mem 0xa8401000-0xa8401fff irq 11
at device 2.0 on pci4
iwi0: Ethernet address: 00:13:ce:b7:ea:8
That works just fine it seems.
But then:
%iwicontrol iwi0 -r
Radio is ON
So, now that the driver is loaded, both if_iwi and acpi_ibm think the
card is turned on, but there is no firmware loaded.
Loading a firmware and then using either `ifconfig iwi0 up' or
`dhclient iwi0' does absolutely nothing.
I've tried various things with the kernel and BIOS but with no luck.
here is my uname:
FreeBSD LIGHTBULB.LOCAL 6.0-RELEASE-p4 FreeBSD 6.0-RELEASE-p4 #19: Mon
Feb 20 15:06:16 EST 2006
[EMAIL PROTECTED]:/usr/obj/usr/src/sys/LIGHTBULB i386
Keep in mind, this also happens on GENERIC.
So, is this a bug in FreeBSD or a quirk in the laptop? I've pondered
whether to submit a PR but I'm not sure what exactly is going on here.
Even disabling the card in the BIOS, acpi_ibm will still indicate that
wlan is turned on.
If anyone can clue me in here, please please do so. Until then I'm
surfing with an atheros card :)
Best Regards,
Nathan Lay
