Hard poweroff was needed. The last line on the console was: input: HP WMI hotkeys as /class/input/input11 After commenting out hp-wmi in /etc/modules the system booted correctly. After the successful boot I tried loading the module manually using modprobe, which resulted in: input: HP WMI hotkeys as /class/input/input11 iwlagn: Radio Frequency Kill Switch is On: Kill switch must be turned off for wireless networking to work. wlan0: No ProbeResp from current AP 00:14:c1:38:e5:15 - assume out of range iwlagn: Error sending REPLY_ADD_STA: enqueue_hcmd failed: -5 mac80211-phy0: failed to remove key (0, 00:14:c1:38:e5:15) from hardware (-5) iwlagn: Error sending REPLY_ADD_STA: enqueue_hcmd failed: -5 mac80211-phy0: failed to remove key (1, ff:ff:ff:ff:ff:ff) from hardware (-5) I also noticed that /sys/bus/platform/devices/hp-wmi/dock is missing. And I lost my wireless connection. Difference between loading hp-wmi from /etc/modules and manually could be that normally wlan is started _after_ /etc/modules is processed. So with the hang wlan was not yet active, while for the manual modprobe wlan was active. With 2.6.28 hp-wmi works perfectly. System is running x84_64, Debian Lenny. Cheers, FJP
