I think this bug might very well be what I am experiencing on my HP EliteBook 2540p too. Booting generally works well with the Squeeze stock bigmem kernel:
$ dpkg -l linux-image-2.6.32-5-686-bigmem Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Description +++-==================================-==================================-==================================================================================== ii linux-image-2.6.32-5-686-bigmem 2.6.32-30 Linux 2.6.32 for PCs with 4GB+ RAM (But very often, randomly is black with the linux-image-2.6.37-trunk-686-bigmem kernel from experimental when booting) However, with the 2.6.32 kernel I still have the black screen problem when the laptop returns from sleep mode (I haven't tried hibernate). Actually of two kinds: one is where the screen brightness is not properly set which I can overcome by switching consoles with Ctrl-Alt-F1 and then back to Ctrl-Alt-F7. But, the other is the here filed black screen problem (after which the only solution I found is the use the power button to shut the laptop down). $ uname -a Linux toxbank53 2.6.32-5-686-bigmem #1 SMP Wed Jan 12 04:40:25 UTC 2011 i686 GNU/Linux $ lspci | grep Graphics 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) (with -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 d0 00 00 00 00 0c 00 00 c0 00 00 00 00 20: 59 50 00 00 00 00 00 00 00 00 00 00 3c 10 08 70 30: 00 00 00 00 90 00 00 00 00 00 00 00 0a 01 00 00 $ lsmod | grep i915 i915 222798 2 drm_kms_helper 18309 1 i915 drm 112720 3 i915,drm_kms_helper i2c_algo_bit 3497 1 i915 video 14605 1 i915 i2c_core 12696 5 i915,drm_kms_helper,drm,videodev,i2c_algo_bit button 3598 1 i915 Egon -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
