ok., so - stepwise. Unpack the ivtv-0.7.0 driver:
cd /usr/portage/media-tv/ivtv
ebuild ivtv-0.7.0.ebuil unpack
cd /var/tmp/portage/ivtv-0.7.0/work
and apply the attached patch:
patch -p0 < ivtv-0.7.0.diff
it should be without any error messages.
Then return back:
cd /usr/portage/media-tv/ivtv
ebuild ivtv-0.7.0.ebuild install
ebuild ivtv-0.7.0.ebuild merge
Or, you can do the same with ivtv-0.7.1 (preferred way, even when ivtv-0.7.0
is not in portage tree yet - you can prepare your own ebuild from
ivtv-0.7.0.ebuild:
copy the directory /usr/portage/media-tv/ivtv with whole content
into /usr/local/portage
(suppose PORDIRE_OVERLAY is defined in your /etc/make.conf as this dir)
rename ivtv-0.7.0.ebuild to ivtv-0.7.1.ebuid
create the digest:
cd /usr/local/portage/media-tv/ivtv
ebuild ivtv-0.7.1.ebuild digest
And the rest is the same, i.e. unpacking, patching by the attached
ivtv-0.7.1.diff, installing and merging.
That is.
Good luck.
btw: my situation was: without the patch applied the boot process went
smoothly until startup of udev, then it stopped, waited for a while and then
the error message (something as like as 'error loading firmware') appeared.
The whole computer was totally frozen - no mouse, no keyboard, no response
via network. Only reset and power buttons worked... If your PC does something
similar, this patch(es) might help as well.
After the application of the patch it is so far ok., no lock-ups.
