commit bfc913682464f45bc4d6044084e370f9048de9d5 upstream. Eiger machine vector definition has nr_irqs 128, and working 2.6.26 boot shows SCSI getting IRQ-s 64 and 65. Current kernel boot fails because Symbios SCSI fails to request IRQ-s and does not find the disks. It has been broken at least since 3.18 - the earliest I could test with my gcc-5. The headers have moved around and possibly another order of defines has worked in the past - but since 128 seems to be correct and used, fix arch/alpha/include/asm/irq.h to have NR_IRQS=128 for Eiger. This fixes 4.19-rc7 boot on my Force Flexor A264 (Eiger subarch).

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.
