[1.] One line summary of the problem: zswap with z3fold makes swap stuck [2.] Full description of the problem/report: I've enabled zwswap using kernel parameters: zswap.enabled=1 zswap.zpool=z3fold When there is issue, every process using swapping is stuck. I can reproduce almost always in vanilla v5.3-rc4 running tool "stress", repeatedly. Issue starts with these messages: [ 41.818966] BUG: unable to handle page fault for address: fffff54cf8000028 [ 14.458709] general protection fault: 0000 [#1] SMP PTI [ 14.143173] kernel BUG at lib/list_debug.c:54!

Instead, it will create abstract handles (3 per page) which will contain pointers to z3fold objects. Thus, it will be possible to change these pointers when z3fold page is moved.

Origninally I noticed the problem in other machines (Fedora 30). I guess any amount of memory pressure and zswap activation can cause problems. Test machine does only have whatever comes from install and whatever is enabled by default. Then I've also enabled serial console "console=tty0 console=ttyS0". Enabled passwordless sudo to help testing and then installed "stress." stress package version is stress-1.0.4-22.fc30 [8.1.] Software (add the output of the ver_linux script here) $ ./ver_linux If some fields are empty or look unusual you may have an old version.

/sys/module/zswap/parameters/enabled' Sometimes stress can die just because it is out of memory. Also some other programs might die because of page allocation failures etc. But that is not relevant here. Generally stress command is actually like: stress --vm 6 --vm-bytes 228608000 --timeout 10 It seems to be essential to start and stop stress runs. Sometimes problem does not trigger until much later. To be sure there is no problems I'd suggest running stress at least an hour (--timeout 3600) and also couple of hundred times with short timeout. I've used 90 minutes as mark of "good" run during bisect (start of). I'm not sure if this is only one issue here. I reboot machine with kernel under test. Run uname -r and collect boot logs using ssh. And then ssh in with test script. No other commands are run. Some timestamps of errors to give idea how log to wait for test to give results. Testing starts when machine has been up about 8 or 9 seconds.
