Subject: [PATCH 3.4 20/65] ipr: Increase default adapter init stage change timeout

From: Brian King <brking@...ux.vnet.ibm.com>

3.4.110-rc1 review patch.  If anyone has any objections, please let me know.

------------------


commit 45c44b5ff9caa743ed9c2bfd44307c536c9caf1e upstream.

Increase the default init stage change timeout from 15 seconds to 30 seconds.
This resolves issues we have seen with some adapters not transitioning
to the first init stage within 15 seconds, which results in adapter
initialization failures.
