Can't reproduce this on 5.0 i386.
Will check for 4.15 i386, if it's still OK I will just close this.

[Kernel-packages] [Bug 1802495] Re: lttng-smoke test failed on i386 4.18 kernel

2019-05-20 Thread Colin Ian King
Course bisect, this does not work with stock upstream kernels since at
least 4.7-rc1.  For now I'm going to disabled this part of the lttng
tests until I can get it to work again with stock 4.8+ kernels.

@Sam, am I missing something, but has this been failing for a while and
it's not been noticed?

And for amd64 bionic+ it fails to generate syscall info too.

2019-05-20 Thread Colin Ian King
It appears that syscalls are not available on i386, got zero syscalls on
bionic, cosmic, disco. It works OK on xenial.

sudo lttng list --kernel --syscall

..produces zero syscalls.
