Title:
ubuntu_zram_smoke test will cause soft lockup on Artful ThunderX ARM64
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Artful:
Fix Committed
Status in linux source package in Bionic:
Fix Released
Bug description:
== SRU Justification ==
Enabling virtual mapped kernel stacks breaks the thunderx_zip driver.
On compression or decompression the executing CPU hangs in an endless
loop. The reason for this is the usage of __pa() by the driver that
does not work for an address that is not part of the 1:1 mapping.
== Fix ==
The patch in comment #12 fixes it.
To reproduce the bug (and test the new kernel), see comment #9.
== Regression Potential ==
The patch affects only the thunderx_zip driver (that is already in a
completely broken state), so the regression potential is low.
---
This is a POTENTIAL REGRESSION.
This test has passed with 4.13.0-36.40, but not 4.13.0-37.42
The test will stuck with error message in dmesg:
