- Subject: Systemtap is broken on latest ElRepo LT kernels (4.4.x)
Hi, All!
I've tried all systemtap versions 3.x and 4.x for ELRepo LT-kernels, latest
kernels are not supported, for example 4.4.169, 4.4.172 (last one) but it
is working on 4.4.145 !
If it's known bug, please, point me to the thread
I've builded systemtap on the same machines where I trying to use it and
got following errors:
# stap -ve 'probe begin { log("hello world") exit () }' 2>&1 | less
