When booting into the kdump/kexec kernel, pHyp and vios are not prepared for the initialization crq request and a failover transport event is generated. This is not handled correctly. At this point in initialization the driver is still in the 'probing' state and cannot handle a full reset of the driver as is normally done for a failover transport event. To correct this we catch driver resets while still in the 'probing' state and return EAGAIN. This results in the driver tearing down the main crq and calling ibmvnic_init() again.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
