this is happening whenever I try to run htop in lxterminal2 and/or xfce terminal.
simply typing at prompt results in Segmentation fault or it runs for a bit and then cores.

@amaztech @lyvivian0077 hi, judging from the above stack trace, this is a kernel crash. A userspace app like htop is not supposed to be able to produce this kind of crash, so this is a sign of a kernel bug. By the looks of do_sys_open and proc_reg_open, the crash is happening when htop is trying to open a file in /proc, which is a virtual filesystem managed by the kernel.

This bug should be reported back to your distro, so thay can redirect it to their kernel teams, and the possibly upstream.

If the crash happens frequently, try running htop on top of strace, strace htop 2> trace.txt — it should show what file in /proc htop was trying to read when the kernel crash happened, and this might help them debug the issue.
