Bug Description
Issue spotted on Bionic 4.15 ARM64 nodes, these tests have failed on both Moonshot and ThunderX nodes
zram01 7 TINFO: filling zram3 (it can take long time)
zram01 1 TBROK: test killed, timeout! If you are running on slow machine, try exporting LTP_TIMEOUT_MUL > 1
And this failure in zram01 is causing issue to zram02 / zram03 test.
We have tripled the timeout for this test on KVM instances, but as these two are bare-metal nodes, so the timeout multiplier is still the same (5mins)
It's better to check for other kernels to see if these ARM64 nodes will fail on them.
And we might need to set the timeout multiplier regardless if it's a KVM or not.

This issue can be found on B-AWS-5.0 (5.0.0- 1022.25~ 18.04.1) instance t2.small as well.
These tests will fail on this instance even with 15 minute timeout.
