Issue #2484 has been updated by davshao.
File acer_725_0687_dmesg.txt added
I just encountered an almost identical bug on an Acer Aspire One 725-0687, an AMD C-70 APU machine. This machine is x86_64, has acpi enabled.
Using master through:
Date: Fri Jan 25 23:48:59 2013 +0100
kernel/mfi: Sort commands by opcode.
and doing a full make buildworld and make buildkernel, the machine hangs at the same line as the Ideapad used to. Once again the workaround is to compile a custom kernel with the virtio device lines commented out.
Attached is a dmesg for the machine.
Bug #2484: virtio hangs boot of i386 Ideapad with acpi disabled
For a Lenovo Ideapad netbook (i386) with acpi disabled using master commits through
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)
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: <math processor> [tentative] on motherboard
npx0: INT 16 interface
The boot problem was bisected to be after:
Date: Sun Jan 6 20:01:27 2013 +0800
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.
