Comment 26 for bug 1828166

Hello IBM,

I have built a kernel for tests with the patches mentioned in the previous comment:

perf record: Fix s390 missing module symbol and warning for non-root users
perf machine: Read also the end of the kernel
perf machine: Update kernel map address and re-order properly
perf machine: Set main kernel end address properly
perf machine: Don't search for active kernel start in __machine__create_kernel_maps
perf machine: Generalize machine__set_kernel_mmap()

The packages for s390x can be found at:
https://people.canonical.com/~ksouza/lp1828166/bionic/

Could you please test the kernel from the link above if it fixes the problem?

Thank you.
