To make matter worse it looks like Patch 5 doesn't install correctly - two drives get left behind that need manually removing.
If these are 2008 R1 and 32-bit servers, we've seen random bugcheck 8E crashes reported to us. Investigation is still ongoing although we can't really investigate anything there without actual data .
What we're missing are having systems configured to save full dumps, not just kernel dumps or minidumps. So, until we have that data that particular issue isn't progressing.
If this is the same issue as what you experienced, your data could help us.
The second comment you made sounds very presumptuous, but if it's something you wanted to verify was a problem or not I suggest calling Support. Be cautious when taking it upon yourself to just remove drivers manually, you could leave your system unbootable.
All the servers crashing and with really poor performance have been 32bit 2008 R1. I'm just uploading a full dump to my service request at present.
That second comment should be doesn't un-install correctly in some cases - even when you remove patch 5 and install patch 4 it leaves behind that problem sys files which still get used leading to further BSODs. That still happens even if you reboot between the un-install and install. It doesn't seem to happen ever time - but most of the time.

It's an important lesson to learn about our software as we adopt a shared driver technology in our products.
Installing our products will often upgrade the shared driver technology. It never downgrades.
When any product installs our shared driver technology, a reference counter is incremented that tells us which products are using which drivers. And, when you uninstall our products that reference counter is decremented.
Only when the reference counter is 0 will the drivers actually be uninstalled. In other words, to downgrade our shared driver tech you must remove ALL products that are using it.
