hvr1300 problems resuming from hibernation

hvr1300 problems resuming from hibernation

[Michael Melchert]

Hello all,

starting from linux kernel 2.6.29 kaffeine had trouble
locking on to different DVB channels on a hvr1300.
On 29/08/09 I pulled the mercurial repository and built modules
from those sources. Things are basically OK running under
2.6.30 and 2.6.31-rc7, that's what I tested.
Only problem that I encountered is that the resume from
hibernation doesnt work anymore, though it worked with
the code base included with the kernel 2.6.28.
Here are a couple of lines that the kernel spat out during the
resume:

there seems to be a problem resuming communication on the i2c bus
playing with kaffeine after the resume leads to:

tried to figure out what goes on on the cx22702 and it seems to be
re-initialisation
that fails b/c i2c bus craps out.

can somebody comment on that?
