Hi List,
Moving from VDR 1.6 to 2.06 for HD (DVB-T2) and seeing regular kernel oops with
the PCTV nanostick 290e when using DVB-T2.
Unfortunately this seems to kill the receiver until a reboot. It happens while
the system is idle.
I wondered if anyone else has a similar experience, or is this a
test-machine/configuration specific problem?
The kernel is 3.0.76 (SLES 11 SP3)
The oops always seems to happen after this log entry with the same diagnostics
- below
"ERROR: can't set filter (pid=18, tid=40, mask=C0): Cannot allocate memory"
If using an identical configuration to my current 1.6 but without the HD stick
I don't see the problem.
I tried a couple of the latest kernel versions in the same series 3.0.101..
with the same result.
I might see if I can build suitable later kernels too, not sure if that's
helpful
- does anyone know or confirm reliable operation on a alter kernel ?
Is there a vdr, kernel or other tweak I need ?
