Bug#585910: linux-2.6: Blank screen at startup with 'Intel Corporation Core Processor Integrated Graphics Controller'

[Andrew Lee (李健秋) <ajqlee@debian.org>]

Package: linux-2.6
Version: 2.6.32-10
Severity: important

Hello, kernel maintainers,

Kernel version since 2.6.32-10 gets blank screen at startup on a 
thinkpad X201i laptop which comes with an "Intel Corporation Core 
Processor Integrated Graphics Controller".

Kernel parameter 'i915.modeset=0' solved the blank screen at startup, but
machine got hangs up after initrd loaded while starting up services.

The output of 'lspci -n' indicate this "Intel Corporation Core
Processor Integrated Graphics Controller" is:

	00:02.0 0300: 8086:0046 (rev 02)

And the output of 'lspci -x':
	00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02)
	00: 86 80 46 00 07 04 90 00 02 00 00 03 00 00 00 00
	10: 04 00 00 f2 00 00 00 00 0c 00 00 d0 00 00 00 00
	20: 01 18 00 00 00 00 00 00 00 00 00 00 aa 17 5a 21
	30: 00 00 00 00 90 00 00 00 00 00 00 00 0b 01 00 00

This problem can be easily reproduced with later version even with 
2.6.34-1~experimental.2, but cannot be reproduced with 2.6.32-9.

I am luckly got such a machine here, I'd glad to help on further tests.

Best regards,

-Andrew
