I think at this point we should put it down to something spurious, or maybe it was specific to having run an older kernel, or something. Unless it can be reproduced, I don't see much point in spending more time on it - I haven't noticed it happening again recently. That said, I tend not to reboot this platform very often! -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
