If it's a culture problem and the C-suite is aware of it, then one reason to buy a company with a working software stack is to percolate their culture into your company so you can be successful.

Hopefully the ceo of the acquired company gets a director role in AMD then at least, not subordinated a supposedly subpar cultured director already in AMD

I have a friend working there and it's a bunch of old curmudgeons stuck in their way. Good luck changing culture with a single acquisition

The company I used to work for is doing this to the engineering org in my current employer. It requires the leadership from the old company to be embedded in very senior positions, and it requires buy-in from the existing C-suite. There's a lot of backroom politics to change culture along with a bunch of work to prove yourselves to people who aren't involved in the backroom. There have been a bunch of points at which I didn't think it would continue but so far the original team has been pretty successful at rising.

Think of it as a reverse McDonnell-Douglas.

I also have this impression. The software problems that are plaguing AMD are in the "less than $10 million" range, if they hired the right people to work on the most severe bugs in their GPU drivers and let them do their job.
