Dear colleagues, in the process of upgrading my home router I'm trying to utilise Intel D2500CC mini-ITX motherboard[1]. Both stable/9 and head suffer from no scrolling issue: from the beginning of booting the kernel, all output overrides the last line on the screen, while others keep the loader phase. Provided the board has multiple serial ports and the final target (headless

...files, the output is almost entirely the same, though in the working case, it had AT_frame_base( rsp ), while the broken case had AT_frame_base( rbp ). Some of the PC extents are different, but in ways that look reasonable. For the location of "r" in the working case, it has AT_location( fbreg -4 ), with AT_location( fbreg +28 ) in the broken case. These locations both seem correct, based on an eyeballing of the assembly output, so there's nothing obviously wrong there, either. > > I'd be delighted to hear any suggestions or pointers! > > Thanks, > -matt >...

Hi,   I want to list some additional information on this.   The variable collection I am looking at is, "variables 'declared' in scope".   1. When I traverse the MachineInstructions in the LexicalScopes ranges, and check for variables, I get variables used in this scope.      The variables listed include variables which may not have been declared in the scope. (for example
