Lenovo X60s freezes during boot sequence

[DSHR]

Binary package hint: linux-image-2.6.27-2-generic

System freezes during bootup sequence during "loading hardware drivers"

Booting without splash gives a hint where the freeze occurs ...

Below is a "correct" dmesg output. When freezing the system stops somewhere after iwl3945, before HDA ...

Hi DSHR,

I'm curious if you'd take a look at bug 267002 and bug 263059 . I'm wondering if this might be a possible duplicate of those as I see you also are using the iwl3945 driver. Each comment about some possible workarounds that you may want to try. Please let us know your results. Thanks.

[DSHR (s-heuer)]

I checked the other bugs and I'm now quiet sure it is not related to the ultrabase. I still experience the problem - even if booting without being docked. I boot without splash so I see the freeze is very near the lines

[ 25.734346] iwl3945: Detected Intel Wireless WiFi Link 3945ABG
[ 25.829057] iwl3945: Tunable channels: 13 802.11bg, 23 802.11a channels

The exact loading of modules seems to be different from boot to boot.

Currently the is a chance of 50% that the system is not going to lockup during boot. I'm going to disable wifi at boot time and see if that helps.
I'll check the new firmware too ...

[DSHR (s-heuer)]

After upgrading the firmware it took me 3 boots to start the system successfully. After checking the dmesg output below I think that loading the firmware takes place 20 seconds after the lockups. I'll be booting with radio off and see if that helps ...

Hi DSHR,

Do you see any improvements with this bug using the newer 2.6.27-3 kernel? Thanks.

[DSHR (s-heuer)]

I had a couple of good boots (5-10) and then 2 failures in a row. Switching off Radio does not seem to help. The new kernel makes no difference either. Maybe I should reinstall the system - it has made its way from gutsy to hardy betas and now to intrepid.

I had absolutely no freezes during normal system operation.

[DSHR (s-heuer)]

As far as I can see, the systems locks during udevadm settle. Any suggestions as how to debug that any further?
