- the sound is dead. It is supposed to be an hda_intel sound, but
nevertheless, alsa reports "no such device". The kernel log reveals
"hda-intel: no codecs initialized",

Any messages about modem init failure? There were problems around
2.6.19/2.6.20 (IIRC) which would cause audio codec init failure unless
the modem codec is disabled. (I think that the parameter which is needed,
if that's the problem, is "probe_mask=1", but check with "modinfo
snd-hda-intel".)

Update on this: It's a bug in the hda-intel kernel module. The problem
seems to be that the chipset reports one pin that has zero connections, and
this confuses the kernel module by aborting the scan for an output that
doesn't have a DAC attached to it. I hacked up the module, and now it
works. I'll send out a kernel patch for this ASAP.

Sounds like -stable material to me...

- Last but not least, wireless seems to cause trouble as well. This is an
(according to lspci): intel PRO/Wireless 3945AGB Network Connection

Noting the later posting saying "Debian"...
# aptitude install wpasupplicant firmware-ipw3945 ipw3945d
You'll also want the ipw3945-module-* for your kernel (given a
Debian-built kernel) or ipw3945-source.

Been there, done that. No avail. I also fetched the latest ipw3945 sources
and recompiled this from scratch, but haven't found any working
configuration.

:-\

I even tried without *any* encryption for the wireless, but
still no-go. iwconfig reports the router, and gives me an excellent link
quality, it just won't connect.

Worksforme. In /etc/network/interfaces, something like this:

iface wlan0 inet dhcp
pre-up invoke-rc.d ipw3945d restart
wpa-driver wext
wpa-bssid xx:xx:xx:xx:xx:xx
wpa-channel xx
wpa-ssid example-ssid-string
wpa-proto RSN
wpa-pairwise CCMP
wpa-group CCMP
wpa-key-mgmt WPA-PSK
wpa-psk long_hex_string

The interface appears as an Ethernet interface; I have a udev rule which
renames it, matching on the MAC address.

(Your router will need to be configured for WPA2.)

Alternatively, use a wireless tree snapshot and firmware-iwlwifi.

(The device will appear as two interfaces, wlan0 and wmaster0, with this
driver.)

Hmm, ok, I'll try whether that works any better. The ipw3945 seems to be
pretty unstable. At times, it really locks up the CPU, etc.

I've never seen that here...
