Upgraded to v6.0.0 now Illegal instruction error
Using both 2020.1 and 2020.2a The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) linux running under virtualbox on windows10 machine and previous version of Hashcat 5.1.0 was working; did a 'apt upgrade' and packages updated to v6.0.0 but now getting when running hashcat this error:

Initialized device kernels and memory...Illegal instruction

googling and trying to update/reinstall openCL libraries and such with no success. Any suggestion appreciated.

In the past version need to use --force but this seems deprecated in v6.0.0

Why are you not running hashcat on your windows system?
I could do that but would prefer to keep pentesting system contained in VM. Might have to resort to that if no go on this moving forward.
Same configuration on my desktop works; laptop I use for mobile pentesting has the issue so I assume it doesn't like the mobile processor. As @undeath suggested I've resorted to cracking on the Windows host rather than the The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) VM in virtualbox.

Just providing an update in case someone else runs into same issue and doesn't want to spend hours like me on trying to resolve when a simple solution like using the Windows host works.
