Hello, Steps to reproduce with dmesg output: # echo "7 4 1 7" > /proc/sys/kernel/printk # modprobe b2c2-flexcop b2c2-flexcop: B2C2 FlexcopII/II(b)/III digital TV receiver chip loaded successfully # insmod b2c2-flexcop-pci.ko debug=0x1f flexcop-pci: will use the HW PID filter flexcop-pci: card revision 2 b2c2_flexcop_pci 0000:04:00.0: PCI INT A -> GSI 21 (level, low) -> IRQ 21 new wr: 208: 00000000 new wr: 210: c259b2ff Then it hangs and I have to reset the machine. This seems to be the beginning of the communication with the Flexcop chip. The commands are executed in flexcop_reset(). System: DVB PCI card: TechniSat DIGITAL SkyStar 2 Rev. 2.8B with Chip FLEXCOP IIB Is there a difference between Rev. 2.8 and 2.8B? Only 2.8 is referenced in the sources. Mainboard: D945GCLF2 with Intel Atom 330 OS: Gentoo Linux 64-Bit Kernel: Linus' git tree (after 2.6.33-rc3), but it didn't work at my first try, which is some time ago, with a Gentoo Kernel based on the stable 2.6.27.12. # lspci -vnn 04:00.0 Network controller [0280]: Techsan Electronics Co Ltd B2C2 FlexCopII DVB chip / Technisat SkyStar2 DVB card [13d0:2103] (rev 02) Subsystem: Techsan Electronics Co Ltd B2C2 FlexCopII DVB chip / Technisat SkyStar2 DVB card [13d0:2103] Flags: bus master, slow devsel, latency 32, IRQ 10 Memory at 50100000 (32-bit, non-prefetchable) [size=64K] I/O ports at 1000 [size=32] Kernel modules: b2c2-flexcop-pci I hope someone has an idea or can give me a tip how to find the problem.
