I think I have a sick Philips DSR6000, its at 3.5, with original drive and turbonet card. Its also got got the CSO tivoapp patch. Day to day it appears to work ok, but if I do Messages & Setup > Settings > Phone > Change Dialing Options causes the unit to reboot. Make Test call also causes a reboot AFTER the call completes. Many tivoweb operations cause the unit to reboot too.
I did do mfscheck which reported no errors and mfsassert -please, but it still has the issue ... whats next?
