[Motorola Atrix 2] Ravikirancg:
Here are a few things that might help.

kmsg when kexec boot up failed: http://www.mediafire.com/download.php?95raby988dvch74 (just open it with a text editor. It is corrupt but you can make out quite a lot.)

The dmesg for stock ics: http://www.mediafire.com/view/?z4pibf2at3u4i7e (Going through this will give you better idea as how things should be.)

And the panic msg after I soft reset it after a black screen: http://www.mediafire.com/view/?z4pibf2at3u4i7e (When I get a black sscreen, I hold vol up+ vol down+ pow for about 10 secs. that soft resets my phone and a panic msg is generated which I retrieve.)

From the kmsg, here is something interesting that appears to be the cause. (Note: I have made some edits to make it readable, not completely readable though.)

The issue appers to be regarding omapfb (frame buffers). might be an issue with the command line. wang's kernel uses

root=/dev/ram0 rw mem=1023M@0x80000000 console=null vram=10300K omapfb.vram=0:8256K,1:4K,2:2040K init=/init ip=off mmcparts=mmcblk1:p7(pds),p15(boot),p16(recovery),p17(cdrom),p18(misc),p19(cid),p20(kpanic),p21(system),p22(cache),p23(preinstall),p24(webtop),p25(userdata),p26(emstorage) mot_sst=1 androidboot.bootloader=0x0A74

However, using

root=/dev/ram0 rw mem=1024M@0x80000000 console=ttyO2,115200n8 init=/init ip=off mmcparts=mmcblk1:p7(pds),p15(boot),p16(recovery),p17(cdrom),p18(misc),p19(cid),p20(kpanic),p21(system),p22(cache),p23(preinstall),p24(webtop),p25(userdata) mot_sst=1 androidboot.bootloader=0x0A73

might solve.

Also, the following keeps repeating

PVR_K:(error):BridgedDispatchKM: Initialisation failed. Driver unusable

but PVR_K is related to display (I guess) and that again takes us back to omapfb.

Put in your thoughts as well but try to keep the thread clean.
