Symptoms depend on the product version:
- Acronis Cyber Backup 12.5 builds 16180, 16318, 16327, 16342, 16343 contain build 0.7.127 – SnapAPI module will not compile on kernel 5.8 and later
- Acronis Cyber Protect 15 builds 24426, 24508, 24515 and later contain SnapAPI build 0.7.133 which imminently leads to kernel crash and the following error:
cannot execute binary file: Exec format error
when trying to execute any binary file.
Same result for SnapAPI build 0.7.134
5.8 kernel has major make_request changes, leading to rerouting all device IO after make_request from Acronis software.
