[Bug 1584935] [NEW] Backport cxlflash patch related to EEH recovery into Xenial SRU stream
You have been subscribed to a public bug:
Request to backport cxlflash EEH patch to Xenial SRU
When a cxlflash adapter goes into EEH recovery and multiple processes
(each having established its own context) are active, the EEH recovery
can hang if the processes attempt to recover in parallel.
After debugging the problem, patch has been upstreamed for this issue and the system has been rebooted with the fix for the problem
---Steps to Reproduce---
Injecting EEH when multiple processes are active can trigger the issue
Stack trace output:
