Revision ea7f665612fcc73da6b7698f468cd5fc03a30d47 authored by Rafael J. Wysocki on 08 June 2013, 00:55:07 UTC, committed by Linus Torvalds on 08 June 2013, 01:33:12 UTC
Commit 9f29ab11ddbf ("ACPI / scan: do not match drivers against objects
having scan handlers") introduced a boot regression on Tony's ia64 HP
rx2600. Tony says:
"It panics with the message:
Kernel panic - not syncing: Unable to find SBA IOMMU: Try a generic or DIG kernel
[...] my problem comes from arch/ia64/hp/common/sba_iommu.c
where the code in sba_init() says:
acpi_bus_register_driver(&acpi_sba_ioc_driver);
if (!ioc_list) {
but because of this change we never managed to call ioc_init()
so ioc_list doesn't get set up, and we die."
Revert it to avoid this breakage and we'll fix the problem it attempted
to address later.
