Hello,
It seems, there I have some timing problems with ivtv driver. My box: Abit
AV-8 Third-Eye/Athlon64 3200+/1 GB RAM/Matrox-G450/Hauppauge PVR-350, Gentoo
linux, 64-bit mode.
And what goes on:
kernel 2.6.16-gentoo-r9/ ivtv-0.6.2: initialization of PVR-350 mostly
ok (I
will explain later). Success in ~90% cases.
kernel 2.6.16-gentoo-r13/ ivtv-0.6.2: initialization of PVR-350 mostly
ok.
kernel 2.6.16-gentoo-r13-SMP/ ivtv-0.6.2 (yeah, I think about upgrade
to
Athlon64X2): initialization of PVR-350 mostly ok. As previous, ~90% success.
kernel 2.6.16-gentoo-r13-SMP/ivtv-0.6.3: initialization of PVR-350 ok
in ~50%
cases
kernel 2.6.17-gentoo-r3-SMP/ivtv-0.7.0: initialization of OVR-350
mostly
fails (failure probability is cca 10:1).
The most illustrative is the situation for 2.6.16-gentoo-r13-SMP kernel
and
ivtv-0.6.3 (see the included log) - testing 'loop':
-----
modprobe ivtv
rmmod tda9887 ivtv saa7127 tuner saa7115 msp3400 v4l2_common i2c_algo_bit
v4l1_compat tveeprom videodev
----
PVR-350 is (randomly?) properly initialized and (randomly?) the initialization
fails, without any other hw or sw change.
The situation is even worse with kernel 2.6.17 and ivtv-0.7.0; if the
initialization fails, then system is hard-locked afterwards, it produces the
at the end the message:ivtv0: loaded v4l-cx2341-enc.fw firmware (262144 bytes) ivtv0: loaded v4l-cx2341-dec.fw firmware (262144 bytes) ivtv0 warning: 1000 ms time out waiting for firmware ivtv0 warning: failed api call 0x00000080 with result 0xfffffff0 ivtv0 warning: Encoder firmware dead! ivtv0 warning: 1000 ms time out waiting for firmware ivtv0 warning: failed api call 0x00000000 with result 0xfffffff0 ivtv0 warning: Decoder firmware dead! ivtv0: Error initializing firmware! and the whole system is frozen, no keyboard, no mouse, no network, even watchdog and hangcheck-timer are dead, only reset-button can help. But, if it is happening the PVR-350 is initialized properly, it works without any troubles for all combinations of kernel/driver, mentioned above. So, it seems, I have some timing problem, which is going worse and worse with every new version of ivtv-driver. I do not think I have some hw problem (among the ivtv driver all other things work properly, looks rather as like as my PVR-350 card is too lazy at the start. What should I try? Thanks for every help, -- Jan Taimr --------------------------------------- The worst computer virus is an end-user ---------------------------------------
