Confirmation of this is appreciated.
I removed iwl3945 from blacklist and ran your workarround.
I rebooted
Another confirmation. 15 boots without a single lockup - seems to be a
good backup plan. Hard resets are not really healthy for the hard disk
so I hope we will see some kind of workaround for the final?

I tried disabling snd-hda-intel, but I could reproduce the hang.
Interestingly, the hang happened further in the boot, at Activating

Matt, the linux bug has some stats WRT to boot messages from Hernando.
The last hang which I see on screen has more output after iwl3945, but
the last line from iwl3945 is the Tunable channels line.

Hi folks,
I first came across bug #275227 which looks like another dup of this dup; in
bug #275227, we linked to other upstream bugs, to a patch, and we decided to
include the fix in the kernel tree. I also prepared a package with this fix in
my ppa at:

I got a hang in one boot out of 6; not sure whether the patches improve
the situation for you folks or not.

There are no signs of a crash here. An oops should show up on the
console if it were the same bug, correct? It does not. The boot process
just stops with no indication of error. And there is no crash of the
driver is loaded after boot instead. So I doubt this bug is the same as
bug #275227.
either way, the kernel freeze is in 2 days time...

Does this mean we have a workaround?

I tried the blacklist/modprobe approach. It never crashes, and there are no
errors in dmesg.
Also, using the wireless after about 30 reloads of the driver does not crash
it, it works fine.
So I would say this might be related, but is not the same bug.
Thanks for helping clearing this up. :)
