So I'm in the presentation - getting ready to sleep my notebook when all of a sudden it bugchecks.
I have never actually had a bugcheck on my new notebook in all the months I've had it. In fact I think my last bugcheck was on my old Dell D600 many months ago . . . so I was rather surprised . . . the culprit I recognized as (probably) my wireless driver during the bugcheck but I confirmed that after I brought the machine back up and I dropped the dump file in WinDBG.
After the reboot I brought up WinDBG and got this stack:

I'm using the inbox Vista drivers for this Intel Wireless chipset I've got in this thing (Intel PRO/Wireless 3945ABG) . . . probably not the smartest thing to do since I just confirmed that they have a newer version that they released on like 5/25/2007 (ver 22.214.171.124).
MENTAL NOTE: Always update all Internet facing drivers before attending *any* security conference. 🙂
I'm just *guessing* that someone is fuzzing the wireless network . . . call me crazy but I use the wifi fairly regularly and have never had a problem with it - and within 30 minutes of powering up in this session - my box bugchecks. 🙁
Hopefully the new driver will be more resilient . . . hopefully I can suck it down before it bugchecks again. 🙂
What really pisses me off about this is everyone here's using XP and I seem to be about the only guy running Vista and I'm sure the nice bright blue screen caused more than a few smiles / internal laughs from the folks around me who witnessed it. They'll probably think its Vista's fault . . . . sigh . . . it's okay Vista - I still love you.
And now that I think about it - I guess I should be thankful it didn't happen during my presentation on Thursday in front of a few hundred people on the podium . . . still - I think I'll physically switch off the wifi on my notebook during the presentation - just in case.
