I've tried .31-rc1 on my HP 2510p notebook and the only problem I found
was that wireless no longer works. The cause looks to be related to
RFKILL.
Initially when I booted all I got in dmesg was:
cfg80211: Using static regulatory domain info
cfg80211: Regulatory domain: EU

Normally I'd expect to see the following after that (from .30):
iwlagn 0000:10:00.0: firmware: requesting iwlwifi-4965-2.ucode
iwlagn 0000:10:00.0: loaded firmware version 228.57.2.23

So it did not even try to load the firmware...
After the boot completed I tried unloading and reloading iwlagn, and then
I suddenly got:

I then noticed that the wireless led on the notbook was indeed off, but it
was totally unresponsive to any attempts to turn it on.
I also compared loaded modules; for .30:
cfg80211 65944 3 iwlagn,iwlcore,mac80211
iwlagn 113236 0
iwlcore 159172 1 iwlagn

lib80211 7520 1 iwlcore
mac80211 164744 2 iwlagn,iwlcore
rfkill 12276 5 hp_wmi,iwlcore
and for .31-rc1:
cfg80211 90808 3 iwlagn,iwlcore,mac80211
iwlagn 107856 0
iwlcore 167908 1 iwlagn
led_class 5064 3 iwlcore,hp_accel,sdhci
mac80211 167024 2 iwlagn,iwlcore
rfkill 20640 2 hp_wmi,cfg80211
Note that lib80211 no longer gets loaded.
After rebooting into .30 wireless worked again.
Cheers,

Same on HP/Compaq nx6310, caused by hp-wmi module. It's disable
bluetooth and wireless. I must turn it on in Windows XP (in HP tools).
Workaround: don't load hp-wmi. Already I try find how enable it via
/sys like in Windows.

Thanks for narrowing it down.
Well, with 2.6.30 hp-wmi worked together with rfkill without problems.
Looking at the commit logs, it looks like the rfkill rewrite by Johannes
and Alan is the cause here. CCs added.

Hmm, looks like there might be another polarity error, try this:
- int query = BIT(b + 8) | ((!!blocked) << b);
+ int query = BIT(b + 8) | ((!blocked) << b);

This helps. hp-wmi works without any problems.

Thanks Johannes, that makes wireless work again.
However, I just saw another possible issue.
When I disable wireless using the hardware switch and the enable it again
almost immediately after on 2.6.30, I get:
[disable]
iwlagn 0000:10:00.0: Radio Frequency Kill Switch is On:
Kill switch must be turned off for wireless networking to work.

wlan0: RX ReassocResp from 00:14:c1:38:e5:15 (capab=0x411 status=0 aid=1)
wlan0: associated
And without any other action networking is up again.
With 2.6.31 I get this:
[disable]
wlan0: deauthenticating by local choice (reason=3)
iwlagn 0000:10:00.0: Error sending REPLY_ADD_STA: enqueue_hcmd failed: -5

[enable]
usb 3-1: new full speed USB device using uhci_hcd and address 3

A lot uglier with those errors. And after that I have to run ifdown/ifup
before networking is up again (ifup only does not work as it will complain
"interface already configured"):
[ifdown wlan0]
Registered led device: iwl-phy0::radio
Registered led device: iwl-phy0::assoc
Registered led device: iwl-phy0::RX

wlan0: associated
ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready
BTW, would it make sense to bring back the first two lines shown with .30
(or at least the first one):
iwlagn 0000:10:00.0: Radio Frequency Kill Switch is On:
Kill switch must be turned off for wireless networking to work.
IMHO it's good to register the reason for the disconnect.
