Wrong. Banks who provided billions in loans to PE firms for decades, are now getting more cautious. But not because they fear of a failed investment, but certain investors of the bank do and that means problem for the bank. The Banks actually don't care what happens to the company being bought. An investment bank which provides a loan never sits on its debt. They are bundled into financial products like CDO, CLO etc and sold to institutional and wealthy private investors. This bought the rise to a new ''era'' recently, where PE firms set up special investment funds to fund big acquisitions of other PE firms. The reason being the current situation of the financial markets and the general negative mood in the markets.
Example with a retailer from the UK, which turned costly for the investment bank: https://www.youtube.com/watch?v=DKYKT4pvYYA&pp=ygUTZnQuY29tI...
