Hi.  We get the errors below in the kernel logs.

WARNING: Kernel Errors Present
Buffer I/O error on device nbd0, ...: 27 Time(s)
Buffer I/O error on device nbd16,...: 3 Time(s)
end_request: I/O error, dev nbd0, secto...: 13 Time(s)
end_request: I/O error, dev nbd1, secto...: 7 Time(s)
end_request: I/O error, dev nbd10, sect...: 7 Time(s)

I see someone else has reported this error message.  E.g. see:

I'm not sure what we are running in /etc/init.d that could be starting something that triggers this error. And I don't believe we see the same error when we use the same file system under UML (but that may be because we have different kernel options enabled).

Has there been any further thought as to what triggers these error messages? Or do you have any advice on what we can do to try and avoid them?
