Created an attachment (id=27323)
 --> (https://bugzilla.kernel.org/attachment.cgi?id=27323)
.config for 2.6.35 (exactly the same as my working 2.6.34.1)

I just compiled the brand new 2.6.35.

I have a Vaio SR11M with an Intel processor Core 2 Duo Penryn P8400.

When I booted my system, it took about half an hour to reach the console login
(getty). At boot, the whole system is stuck (no cursor blinking anymore,
although I can press CapsLocks and the led will light up). It takes about 5
minutes for udev scripts to run.

After about 7 minutes, the kernel reports that it was unable to load the
iwlwifi-5000-ucode firmware (this is probably another bug, but wifi worked
perfectly with 2.6.34.1). Still, after this the boot process continues but very
very slowly. Every line appears every 2 or 3 minutes, and it seems that the
kernel is doing something.

After waiting for almost half an hour, the system finally boots, I can see the
display manager, but in console 0 (in text mode). Again (although this should
be another topic) I can see ioctl errors about wlan0, my wireless device is not
recognized.

I use Debian Sid (up to date), kernel 2.6.35 vanilla with the same options as
2.6.34.1 (which works perfectly in the exact same environment). My system is
64-bits (Debian amd64).

Any clues why 2.6.35 boots so extremely slowly?

Please find enclosed my .config-2.6.35.
