Is it possible to get an old module to work with 7 kernel?

In 5* and 6* my Olympus camera mounted with umass as an msdos drive (da?s1).

With 7-STABLE umass panics.

Is there some way of making an old umass module work with the new kernel?
Downgrading the whole system for a camera seems rather drastic, but I am not
sure what else to do.

"Stale dependency": When pkgdb -F reports this, it means the dependency is
missing, not that the dependency is obsolete.

Write a PR? Especially now with 7.1 upcoming, detailed problem reports
seem to be in order.

I don't know whether it's possible to downgrade umass that way as I have
no idea what the relevant KPI changes are. You could try and find out, of
course, but it'll likely be more work than downgrading the entire system.

You should fill a PR for this and ask on the freebsd-stable@ mailing
list.

Compile a kernel with WITNESS and all debugging options on, then you
should get a crash dump of the panic.
See

Hope this help.

As it turns out, the Olympus card can be read from my HP printer using the
HP Device Manager from the hplip port. This is not really the right
solution, as it used to possible to read the camera as a flash drive with
umass loaded (which cannot happen at boot to avoid the printer, which must be
a ugen device, being grabbed by umass).
