Any ideas?

 

Thanks!

anyone?

I looked at the trace yesterday, had no clue.  The key question though is are your VM's still working normally?

[IpDo]

Everything works perfectly as far as I can tell.

Then you have 2 options:

 

1. Get a degree in CoSci, scour through the source code for KVM, disassemble the code for your BIOS and any add-in cards, and use that as a basis to try and put the error into perspective.  Or,
2. Don't worry about it.

 

I'll let you decide

Hmmm, Option number 1 sound like a solid choice

 

Thanks anyways!
