Pogoplug v3 PIP and PIP3 segementation fault (1 reply)

Hi,

I have the latest kernel running on my Pogoplug V3 box. I tried both pip and pip3, but both generates segfault.

root@scht:~# uname -r
5.4.101-oxnas-tld-1
root@sch:~# cat /etc/debian_version 
9.13
root@sch:~# pip3
Segmentation fault
root@sch:~# python --version
Python 3.5.3

Here is the segmentation fault trace from the logs:

With previous kernels (last i used was 4.4.176) it worked just fine. Any ideas what can cause this issue with the current kernel?

Thanks
