Symptoms

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

Cause

5.8 kernel has major make_request changes, leading to rerouting all device IO after make_request from Acronis software.

Solution

Acronis Cyber Protect Cloud: support for kernel 5.8 was added in C21.07, Agent 27305. Please update to the latest build. 

Acronis Cyber Protect 15: Support for kernel 5.8 was added in Update 3 (Build 28035) of Acronis Cyber Protect 15. Please update to the latest build.
