[linux-dvb] AW: Re[2]: DVB-C it got worse!

["Frank Meyering" <meyering@imst.de>]

Hi,

try to disable ACPI. Yersterday i did some testing with different kernel
options (ACPI, APIC ...) and encountered some strange problems using APIC
and/or ACPI on my Athlon machine. With APIC enabled it was impossible to
shutdown the X-Server (it crashed during shutdown), and with ACPI enabled
the DVB-Driver doesn't tune. I'm using an Athlon XP 2000 on MSI K7T266Pro2
(VIA KT266A). Without both options (Kernel 2.4.20-rc2 from kernel.org) it
works really nice.

Windows works on the athlon box. (well buggy software, but once I got
it up, channel switch on a encrypted channel takes about 3-4 seconds).

So how can I continue the debugging and fault finding?

Any suggestion on which files to concentrate on, is there any
documentation of the project files?

Can anyone recommend a easy to use diff util?

MB>> Hello again,

MB>> Today I downloaded the latest cvs, since someone reported great

MB>> I'm the guy with "outcommand error 1" in my log.

MB>> Now, with todays cvs I cannot tune at all, even if I let czap run for

MB>> Only "make rmmod" fixes this, and if I reload the driver, it will not

MB>> My config:
MB>> Athlon 1800, Abit KX7-333 (via KT333) DVB-C 2.1 card (known to work in
MB>> my last computer). Kernel Gentoo 2.4.19.

MB>> I have:
MB>> Moved the card around in different pci slots, there's no irq
MB>> conflicts.
MB>> I have tried to compile kernel with and with out APIC
MB>> support, with and without preemptible patch.


MB>> I guess, that a way forward would be to dig up my old P3@910 that used
MB>> to host the DVB-C board, and start all over.
