Outstanding I/O after 10 seconds

[Lukas Ertl]

Hi there,

I've now seen several times the following messages:

WARNING: Final close of geom_dev(da9s1a) still has outstanding I/O after 
10 seconds. Completing close anyway, panic may happen later.

This happens when I run benchmarks on the specified device (like rawio). 
The strange thing is that when I look at what triggers this message, then 
cp->nstart is one less than cp->nend, like there was an additional 
g_io_deliver() on a bio.

Any ideas why cp->nend would be larger than cp->nstart?

cheers,
le
