When does the write error happen and what guest/host are you running ? If it's a regression, would it be possible for you to bisect it ? Is Bug 100661 related to the same hardware ?

Can you please provide a little bit more information ?
When does the write error happen and what guest/host are you running ? If it's a regression, would it be possible for you to bisect it ? Is bug 100661 related to the same hardware ?

--- Comment #2 from Lidong Chen <[email protected]> --- When does the write error happen and what guest/host are you running ? this error happen when the guest os is booting.
the guest os kernel verison is also 4.1.0+.

If it's a regression, would it be possible for you to bisect it ? yes,the old kernel version didn't have the bug. so i will try to find out which patch cause this error.

Is bug 100661 related to the same hardware ?
yes.
