end_request: I/O error, dev sda1, sector 1236704
Hi,
I'm having a filesystem issue in Linux DomUs, on several NetBSD/Dom0
boxes (so it's not related to underlying hardware failures). It used to
happen with 3.0.1-4, and it still happens with 3.1, preventing me from
using Linux domUs on NetBSD dom0.
very much lines like this, a bit while booting, and very much while
using the system (e.g. doing du -sh),
end_request: I/O error, dev sda1, sector 1236704
This is what happens in the logs,
