Subject: [Xenomai-core] Bug in Linux kernel 2.6.37 blocks xenomai threads
Date: Mon, 4 Apr 2011 16:41:58 +0200 [thread overview]
Message-ID: <201104041641.58183.smolorz@domain.hid> (raw)
Hi,
there is a bug in kernel 2.6.37 (fixed in 2.6.37.1, see commit
1cdc65e1400d863f28af868ee1e645485b04f5ed) which blocks RT threads during
creation. They stick to a certain CPU core for a certain amount of time
(sometimes minutes ...) before they are migrated to the proper core and run
as expected.
Philippe, Gilles, maybe you could generate a new i-pipe patch based on the
newest 2.6.37-series kernel. I patched a 2.6.37.6 kernel with adeos-
ipipe-2.6.37-x86-2.9-00.patch and the problem was gone.
