^^^^^^
You want to start a sentence here. Capitalize "The".
Also don't use future tense in commit descriptions (and commit titles).
Simply use present tense. Using future tense makes it confusing if
this is what the code used to do before this change or if the code
is doing this right now as someone is reading the commit in the future with "git log".

I've found it best to describe what's being done as if telling a story.
Break it down into "tell what's happening" and "tell what what's fixed and
how it affects the rest of the system". Something like this:

	Assigning false to block->status.hw overwrites PSP's previous
	hardware status, which causes the PSP to resume operation after
	hardware init.

	Remove this assignment and let the PSP start when it is told to.

Check if the above rendition of your change is correct, and use it if so.

Regards,
Luben
