Subject: X200: Suspend & resume, iwlwifi on 2.6.29-rc3-00697-gae1a25d

Hello!

Using latest git fetch from
  git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
I can suspend and resume!
(-next: does not work for a long time -- what's happening there?)

Though, the first resume takes about 30 seconds, the following ones
resume within 10 seconds.

The iwlagn / iwlwifi driver does not work anymore: ip l s wlan0 up
makes ip hang for about 10 seconds, issuing the following in dmesg:

[22640.752121] iwlagn: Could not load the INST uCode section
[22640.752132] iwlagn: Unable to set up bootstrap uCode: -110
[22645.752062] iwlagn: Could not load the INST uCode section
[22645.752072] iwlagn: Unable to set up bootstrap uCode: -110
[22650.752118] iwlagn: Could not load the INST uCode section
[22650.752128] iwlagn: Unable to set up bootstrap uCode: -110
[22660.752059] iwlagn: Could not load the INST uCode section
[22660.752069] iwlagn: Unable to set up bootstrap uCode: -110
[22660.761456] iwlagn: Unable to initialize device after 5 attempts.
[22660.761581] iwlagn 0000:03:00.0: PCI INT A disabled

I'm using latest microcode:

[10:33] ikn:~# sha1sum /lib/firmware/iwlwifi-5000-1.ucode ~nico/Desktop/iwlwifi-5000-ucode-5.4.A.11/iwlwifi-5000-1.ucode       
f06ff86c8baa8616de584f8b0fff072a9aab6a44  /lib/firmware/iwlwifi-5000-1.ucode
f06ff86c8baa8616de584f8b0fff072a9aab6a44  /home/user/nico/Desktop/iwlwifi-5000-ucode-5.4.A.11/iwlwifi-5000-1.ucode

I'm wondering what's broken with iwlwifi and why the first resume takes so long.
Anyone a good idea?

Sincerly,

Nico
