I have had my line locked to ADSL1 with uncapped upstream (for some reason it doesn't like ADSL2) and I just had loss of broadband due to - according to router log - Kernel Warm Restart
The odd part is that the upstream sync is 896kbps interleaved whereas I thought the limit when interleaved was 888kbps
Second question - what would cause a Kernel Warm Restart on a TG582n which wasn't a router reboot as the log is still there for before that

The 888kbps upstream limit seems to depend on the depth of interleaving applied upstream. On ADSL2+ with interleaving on I have an upstream sync speed of 1197kbps. The telnet stats show interleaving depth=0 (though the FEC error count (not shown here) is non zero).
Occasionally I experience kernel warm restarts, never identified a likely cause - re-sync often at higher speed. Other times sync has been lost but low SNRM was likely in these instances (re-sync at reduced speed).

I've had warm restarts after I've be modifying device details; like removing old devices or assigned static IP address to a device.
