memory corruption problem? running ubuntu-bionic-4.14.52
I'm running ubuntu-bionic-4.14.52-00491-g367dd8955e03-dirty-desktop-mali-2018-07-01.img on a LePotato and running into a kernel panic within a few minutes of activity.
The problem happens randomly and always within a few minutes of start up. I can cause the problem to happen more quickly by running Firefox and browsing to a few web sites, but I think that's just because this application uses memory a lot.
example error messages from console connected via USB UART:
[ 505.655708] Unable to handle kernel paging request at virtual address ffffdf7f709d543b
[ 505.656378] Internal error: Oops - SP/PC alignment exception: 8a000000 [#1] SMP
[ 505.656381] Unable to handle kernel paging request at virtual address ffffa0b91039eb0c
I will attach the complete sequence of console messages if I can.
- is anyone else running into this?
- does this system need a ddr calibration sequence
- do I have a lemon LePotato board?
