help building / install Droid Incredible kernel

[gnychis]

I want to make some modifications to my Incredible's kernel. However, before I start I would like to at least try to rebuild and replace the stock kernel. That way I know that any issues are related to my changes, and not trouble building/installing the stock kernel.

So I went to my Incredible's Software Information and found my kernel version to be:

2.6.32.17-g9a2fc16
htc-kernel@u18000-Build-149 #1

So I went to HTC's android source code page and found the following kernel source code which matches my build:
HTC - Mobile Phones, Smartphones, Cell Phones, PDAs

I pulled the kernel configuration from my phone with:

adb pull /proc/config.gz
gunzip config.gz
mv config .config

Then I made sure to build with the local version properly set:

make LOCALVERSION=-g9a2fc16

Now, the tricky part to me is actually setting up the proper boot.img. I have done two things to extract the original boot.img to get boot parameters and ramdisk. I found my boot partition here:

gnychis@air:~$ adb shell cat /proc/mtd
dev:    size   erasesize  name
mtd0: 000a0000 00020000 "misc"
mtd1: 00480000 00020000 "recovery"
mtd2: 00300000 00020000 "boot"
mtd3: 0f800000 00020000 "system"
mtd4: 000a0000 00020000 "local"
mtd5: 02800000 00020000 "cache"
mtd6: 09500000 00020000 "datadata"

Then I extracted boot.img as follows and split it:

$ adb shell
   $ su
   # cat /dev/mtd/mtd2 > /sdcard/stock_boot.img
   # exit
   $ exit
$ ./split_bootimg.pl stock_boot.img 
Page size: 2048 (0x00000800)
Kernel size: 2274960 (0x0022b690)
Ramdisk size: 167337 (0x00028da9)
Second size: 0 (0x00000000)
Board name: 
Command line: no_console_suspend=1
Writing stock_boot.img-kernel ... complete.
Writing stock_boot.img-ramdisk.gz ... complete.

Then, I combine this ramdisk with my own built version of the kernel as follows:

./mkbootimg --kernel kernel/arch/arm/boot/zImage --ramdisk stock_boot.img-ramdisk.gz --cmdline "no_console_suspend=1" -o boot.img

Then I pushed it to my sdcard as "mystock_incredible_boot.img" and rebooted my phone to recovery mode. In recovery mode, I did:

# flash_image boot /sdcard/mystock_incredible_boot.img
flashing boot from /sdcard/mystock_incredible_boot.img

mtd: successfully wrote block at 200000
mtd: successfully wrote block at 220000
mtd: successfully wrote block at 240000
mtd: successfully wrote block at 0

Then, I rebooted the phone and it never gets past the "htc Incredible" white screen. So then I tried to do some debugging and despite that the only kernel option found in the stock boot.img was "no_console_suspend=1", I found from dmesg that when the phone boots the stock boot.img there are many more kernel options:

<5>[    0.000000] Kernel command line: board_incrediblec.disable_uart3=0 board_incrediblec.usb_h2w_sw=0 board_incrediblec.disable_sdcard=0 diag.enabled=0 board_incrediblec.debug_uart=0 smisize=0 userdata_sel=1  androidboot.baseband=2.15.00.07.28 androidboot.cid=VZW__001 androidboot.carrier=COMMON androidboot.mid=PB3120000 androidboot.keycaps=qwerty androidboot.mode=normal androidboot.serialno=HT042HJ01678 androidboot.bootloader=0.92.0000 androidboot.hardware=inc no_console_suspend=1

So, then I tried packaging it with all of these boot parameters also, and I still do not get past the "htc Incredible" white screen. I'm not sure what I am missing here. Does anyone see anything wrong with what I have done?
