Hey guys,
I recently bought a Technisat CableStar HD2:
lspci -s 04:05.0 -vv -n
04:05.0 0480: 1822:4e35 (rev 01)
Subsystem: 1ae4:0002
Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr-
Stepping- SERR+ FastB2B- DisINTx-
Status: Cap- 66MHz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort-
<TAbort+ <MAbort- >SERR- <PERR- INTx-
Latency: 64 (2000ns min, 63750ns max)
Interrupt: pin A routed to IRQ 20
Region 0: Memory at f6fff000 (32-bit, prefetchable) [size=4K]
Kernel driver in use: Mantis
So to question one:
I read the wiki article[1] to setup my new card and then noticed that
the following drivers are enough:
CONFIG_MEDIA_SUPPORT
CONFIG_VIDEO_DEV
CONFIG_DVB_CORE
CONFIG_MEDIA_ATTACH
CONFIG_MANTIS_CORE
CONFIG_DVB_MANTIS
CONFIG_DVB_FE_CUSTOMISE
CONFIG_DVB_TDA10023
and CONFIG_DVB_PLL (Auto selected)
So my question is now, do I really need for some reason the:
CONFIG_DVB_TDA10021 and CONFIG_DVB_B2C2_FLEXCOP /
CONFIG_DVB_B2C2_FLEXCOP_PCI drivers?
The cu1216 isn't available in 2.6.36 so I guess I don't need this one at
least..
It seems he uses the same card there but in my case just
CONFIG_DVB_TDA10021 seems to not work but I'll test it again later if I
get to it.
To my second question:
I saw two threads [2][3] (unfortunately German only) that I'd have to
patch the kernel drivers or I even have to use other[4]/non-kernel[5]
driver. Is it still necessary or has it been fixed in any of the 2.6.3x
kernels? I didn't test the IR stuff yet so I just ask...
The third thing I noticed is:
Get such a card (Might be even reproducible without the card)
Build the drivers above (at least CONFIG_DVB_TDA10023) as module
Boot and you'll get something like here:

[1] 4992 killed modprobe mantis
That was just a modprobe in this case because I've no serial cable
attached currently so I wasn't able to save the kernel trace.
This also happened with 2.6.{35,34} and IIRC .33 too.
Its the same with TDA10021.
I just saw it has been reported already [6]
The kernel/udev doesn't even load the drivers automatically for some
reason.. if CONFIG_DVB_TDA10023 has been build solid into the kernel
while the rest has been built as module.
