From f2f027c6e9912840020be8b78f037d5c8ac665e0 Mon Sep 17 00:00:00 2001 From: Hugh Dickins Date: Wed, 23 May 2007 14:41:42 -0700 Subject: [SCSI] fix CONFIG_SCSI_WAIT_SCAN=m CONFIG_MODULES=y CONFIG_SCSI=y CONFIG_SCSI_SCAN_ASYNC=y CONFIG_SCSI_WAIT_SCAN=m 2.6.21-rc5-mm2 VFS panics unable to find my root on /dev/sda2, but boots okay if I change drivers/scsi/Kconfig to "default y" instead of "default m" for SCSI_WAIT_SCAN. Make sure there's a late_initcall to scsi_complete_async_scans when it's built in, so a monolithic SCSI_SCAN_ASYNC kernel can rely on the scans being completed before trying to mount root, even if they're slow.

Moves quiesce, thread and interrupt shutdown into aacraid drivers' .shutdown handler. This fix to the aac_shutdown handler will remove the superfluous reset of the adapter during a (clean) kexec. This fix may mitigate the active investigation 'kexec and aacraid broken' but it is unlikely to affect the root cause (issue likely present in both kexec and kdump). This patch reduces the chance the problem will occur with a kexec. The fix for root cause is currently expected to be the minimum value check to the aacraid.startup_timeout driver variable after an adapter reset within aacraid_commit_reset.patch submitted on 05/22/2007 and awaiting testing by Yinghai to confirm.
