Ok. "kernel.watchdog_thresh=30" is a sysctl presentation, i mixed them
wrongly.
Your patch about cmd support for 'watchdog_thresh=30' working. I tested
it: parameter applies and lzma -9 initramfs loading successfully.
If I delete parameter from cmdline - same kernel not boot.

In my case (3.2.32) it cannot compile:
LD arch/x86/boot/compressed/vmlinux
arch/x86/boot/compressed/misc.o: In function `decompress_kernel':
misc.c:(.text+0x993): undefined reference to `touch_softlockup_watchdog'
