Using gcc 4.1.1

The Cam module won't work on driver load. The error is "dvb_ca adaptor 0: PC
card did not respond  :( ". 

Steps to reproduce:
Make sure the CAM module is inserted in the CI slot.
Load the budget-av driver: "modprobe budget-av".

The following log appears in dmesg:

saa7146: register extension 'budget_av'.
ACPI: PCI Interrupt 0000:04:07.0[A] -> Link [LNKB] -> GSI 17 (level, low) -> IRQ 90
saa7146: found saa7146 @ mem ffffc2000019ec00 (revision 1, irq 90) (0x1894,0x0020).
saa7146 (0): dma buffer size 192512
DVB: registering new adapter (KNC1 DVB-C).
adapter failed MAC signature check
encoded MAC from EEPROM was
ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff
KNC1-0: MAC addr = 00:09:d6:6d:5a:f0
DVB: registering frontend 0 (Philips TDA10021 DVB-C)...
budget-av: ci interface initialised.
budget-av: cam inserted A

and after some time:

dvb_ca adaptor 0: PC card did not respond :( 

The steps can repeated if the driver is unloaded using:
modprobe -r budget_av budget budget_ci budget_core


However, if the drivers are loaded and the message "dvb_ca adaptor 0: PC card
did not respond  :( " appeared and I remove the CAM module from the CI, and then
reinsert it again the following messages appear:
budget-av: cam ejected 5
budget-av: cam inserted B
dvb_ca adapter 0: DVB CAM detected and initialised successfully 

After which the CAM module is actually working.

Comment 1 Natalie Protasevich 2007-06-21 22:24:47 UTC

Please test with the latest kernel (2.6.22-rc4), is the problem still there?
Thanks.

Comment 2 Jeroen Asselman 2007-07-29 03:36:51 UTC

with Linux version 2.6.22-gentoo-r2

budget-av: cam inserted A
dvb_ca adaptor 0: PC card did not respond :(

Comment 3 Mauro Carvalho Chehab 2007-11-06 09:46:45 UTC

There where some fixes at the development tree. Could you please try it? The development tree is available at:

Comment 4 Jeroen Asselman 2007-11-06 13:45:43 UTC

fetched the version as of 2007-11-06, however still the same problem

Comment 5 Oliver Endriss 2007-11-07 19:27:53 UTC

(Sorry, due to lack of hardware I cannot be of much help in this case.)
If you have some basic programming knowledge, you might have a look into budget-av.c, ciintf_init(). You  might try whether it helps if you insert delays there.
Please provide a patch if you are able to fix the problem.

whoops - wrong bug ... sorry for bugspamming (please ignore / delete the patch)

Comment 8 Jeroen Asselman 2009-02-03 07:19:08 UTC

The problem seems to be that the power off / on is not happening. The card remains running. 
Is there a command that can be sent so the attribute memory can be re-read?

Comment 9 tlinden 2009-08-22 21:45:37 UTC

I can confirm that this bug still exists in Fedora 10 with kernel

Only if I have the CI and CAM modules installed in the computer, then I get these error messages
