[ https://issues.jboss.org/browse/SWSQE-293?page=com.atlassian.jira.plugin.... ] Filip Brychta resolved SWSQE-293. --------------------------------- Resolution: Done Found better workaround than disabling acpi. Process responsible for stuck booting was IPMI driver (ipmi_msghandler module). IPMI driver is getting some information from acpi so it's possible that it was not running with acpi disabled and therefore not blocking booting. It should be safe to disabled IPMI, here is IPMI doc - https://www.kernel.org/doc/Documentation/IPMI.txt I disabled it according to this article: https://access.redhat.com/solutions/887073 Now all affected blades are booting fine with acpi enabled. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
