Subject: Intermitted "Failed to obtain HW semaphore, aborting" error
Date: Sun, 03 Feb 2013 00:14:15 -0500 [thread overview]
Message-ID: <510DF227.30307@vt.edu> (raw)
[-- Attachment #1: Type: text/plain, Size: 573 bytes --]
Intermittently a couple of nodes in our cluster throw the error "Failed
to obtain HW semaphore, aborting" on boot. When this error occurs we are
unable to use IB on those nodes, unloading and reloading the module
doesnt help. I was wondering what could be causing this error, google
only brings up the source code and no discussion about this error. We
are using OFED-1.5.4, any help in debugging and resolving this issue is
greatly appreciated.
note: I am not subscribed to the list so would appreciate if I am copied
in the replies.
