Can you accumulate all our discussion and create one right-coded, kernelcode-styled patch?

In past - no. But I not test this last  kernel variant with other level.

I think this is similar as decompress:
Kernel stop and wait next try in "default_idle()" for 20-30 sec, and in this moment softlockup detector panics ;)

But without patch for touch_softlockup_watchdog in decompress_unlzma+misc.c it works (try, fail, pause, try, fail, go on).
