Hi, i have a quite annoying problem. Sometimes my dvb-t card works quite well after a boot, but mostly it errors out with: mt352_read_register: readreg error (reg=127, ret==-5) dvb-bt8xx: A frontend driver was not found for device 109e/0878 subsystem 1461/0771 As you can see i have an avertv dvb-t 771 (i worked on the mt352 driver, thanks for wolgang jost for his good work). My kernel is 2.6.12-gentoo-r6. I think the problem maybe has something to do with my mainboard or its bios. I testet some older bios versions and the latest one, but the problem doesn't go away. Even kernelparameters like noapic, acpi=off and pci=bios/nobios,usepirqmask,noacpi don't improve the situation. All modules are working properly except of mt352, as you can see here: bttv: driver version 0.9.15 loaded bttv: using 8 buffers with 2080k (520 pages) each for capture bttv: Bt8xx card found (0).

Does anybody have an idea, how to get this working again? Thanks for any coming answer.
