[Marcelo Cerri]

[Impact]

 * sysdig 0.24.1-1 panics with kernel 5.3 (check console.txt attached).
 * The following fix solves the problem: https://github.com/draios/sysdig/commit/94ca2866d

[Test Case]

 * Install sysdig-dkms and sysdig on a system with kernel 5.3.
 * Load sysdig-probe
 * Start csysdig
 * Increase the load on the system (ie, stress-ng --cpu 8 --io 4 --vm 2 --vm-bytes 128M --fork 4 --timeout 10s)
 * The system panics

[Regression Potential]

 * The change is small and fixes a panic that is easily reproduced.

[Other info]

 * The problem was initially reported on a comment from bug #1853908.

I tested 0.24.1-1ubuntu4~18.04.1 following the same steps listed on the bug description with success. While the previous version (0.24.1-1ubuntu3~18.04.1) easily panics, the new version in proposed was able to run several runs of `stress-ng --cpu 8 --io 4 --vm 2 --vm-bytes 128M --fork 4 --timeout 10s` without problems. The tests were performed on an x86_64 KVM VM with bionic.

The fix for this bug has been awaiting testing feedback in the -proposed repository for eoan for more than 90 days. Please test this fix and update the bug appropriately with the results. In the event that the fix for this bug is still not verified 15 days from now, the package will be removed from the -proposed repository.

The version of sysdig in the proposed pocket of Eoan that was purported to fix this bug report has been removed because the bugs that were to be fixed by the upload were not verified in a timely (105 days) fashion.
