hi folks,
getting the below when loading the dvb budget_ci module. it disables IRQ
#23 which is attached to the card, rendering it useless. i asked the
same question over there and none of them suspect it to be a DVB
problem. some esoteric pci bug perhaps?

Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
