           Summary: b2c2-flexcop adapter fails to register frontends due i2c
                    readreg error
           Product: v4l-dvb
           Version: unspecified
     KernelVersion: 2.6.26.2
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: blocking
          Priority: P1
         Component: dvb-frontend
        AssignedTo: v4l-dvb_dvb-frontend at kernel-bugs.osdl.org
        ReportedBy: jheikkal at gmail.com


Latest working kernel version: 2.6.25.11
Earliest failing kernel version: 2.6.26
Distribution: Archlinux
Hardware Environment: Asus M2N-VM HDMI motherboard, Technisat Cablestar 2 PCI
DVB-C card
Software Environment: 
Problem Description:

With 2.6.26 And later kernels frontend registeration of the Cablestar card
doesn't work. For stv0297 DVB-C frontend dmesg says:

b2c2-flexcop: i2c master_xfer failed
stv0297_readreg: readreg error (reg == 0x80, ret == -121)
b2c2-flexcop: no frontend driver found for this B2C2/FlexCop adapter

So card is found and modules loaded but frontend registering fails so dvb-c
usage is impossible.

Steps to reproduce:

Use 2.6.26 kernel or later
