Bug #2484: virtio hangs boot of i386 Ideapad with acpi disabled
http://bugs.dragonflybsd.org/issues/2484
Author: davshao
Status: New
Priority: Normal
Assignee: vsrinivas
Category:
Target version:
For a Lenovo Ideapad netbook (i386) with acpi disabled using master commits
through
commit 1d0de3d37b9efb6301b10515fd12d922c8602093
Date: Tue Jan 8 19:21:35 2013 +0100
kernel/vfs: Remove some unused variables.
boot hangs after devices:
md0: invalid primary partition table: no magic
Math emulator present
hptrr: RocketRAID 17xx/2xxx SATA controller driver v1.2
hpt27xx: RocketRAID 27xx controller driver v1.0 (Jan 9 2013 12:15:05)
and before
IOAPIC: rman cpu0 0 - 1
IOAPIC: rman cpu0 3 - 95
IOAPIC: rman cpu0 97 - 191
IOAPIC: rman cpu1 24 - 95
IOAPIC: rman cpu1 97 - 191
npx0.nexus0.root0
npx0: <math processor> [tentative] on motherboard
npx0: INT 16 interface
The boot problem was bisected to be after:
commit 42fdf81ee882d38808efe2772a68a9c4991a5f76
Date: Sun Jan 6 20:01:27 2013 +0800
and before:
commit f31f6d84db329735c062a41c0f729843cd4d0b6f
Date: Mon Jan 7 09:48:18 2013 +0100
kernel/hammer: Remove unused variables and add __debugvar.
In addition a workaround is to disable kernel options for virtio for a custom
kernel config:
# VirtIO support
# device virtio # VirtIO core
# device virtio_blk # VirtIO disk driver
# device virtio_pci # VirtIO transport over PCI bus
Attached is a dmesg for the booting configuration with acpi and virtio disabled.
