Ever since I upgraded my Tivo from 120Gb to 300GB (which seemed to go ok - including the LBA48 kernel upgrade), the daily call has failed with "service unavailable". Trying to run nic_config_tivo results in it failing just after "Checking Software Version..." with the message "Segmentation Fault".
I've had a good search, but can't find any mention of "Segmentation Fault" relating to nic_config_tivo. I thought it could have been that my cachecard drivers were too old, and weren't compatible with the LBA48 kernel, but upgrading them (taking the drive out and running nic_install cachecard) didn't make any difference. Interestingly nic_install produces very similar output to nic_config_tivo, and DIDN'T fail at the "Checking Software Version..." step.
Any ideas? (I'm desperate now, as my Tivo is out of guide data, and I'm emigrating TOMORROW!)
