Dear all,
I'm encountering big problems with 3.14.28 when I try to debug my QT
apps with GDB. With 3.10.53 I have no problems with the same apps.
It seems that when I start a debug session sometimes (not every time but
maybe 1 of 2) I have a "Unable to handle kernel paging request at
virtual address" error that is raised by a process (not necesseraly the
QT apps), in this log it was HTOP that was running on a SSH terminal.
The trace is quite long and not sure it can help. I'm on it since
several days, any help will be welcome. Thank you in advance :
