Description

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:

  1. VirtIO support
  2. device virtio # VirtIO core
  3. device virtio_blk # VirtIO disk driver
  4. device virtio_pci # VirtIO transport over PCI bus

Attached is a dmesg for the booting configuration with acpi and virtio disabled.

Could you get a 'pciconf -l -v' from the system, when booted w/o ACPI and
w/o the virtio driver?

Also, when you boot w/ the virtio driver built-in and with bootverbose
enabled, what is the last message you see?

Thanks,

The last lines before the hang when using virtio and bootverbose are:

md0: Malloc disk
kbd: new array size 4
kbd1 at kbdmux0
ndepotmags=5 x mag_cap=29 for crypto op
ndepotmags=5 x mag_cap=29 for crypto desc
crypto: <crypto core>
Pentium Pro MTRR support enabled
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 07:37:18)

The results of pciconf -l -v are:

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.nexus0.root0
npx0: <math processor> [tentative] on motherboard
npx0: INT 16 interface

The boot problem was bisected to be after:

Here's what I know about this bug:

  • It seems to occur on i386 only.
  • The boot hanging occurs randomly. The box I have that exhibits the bug
    boots in 70-80% of the cases and hangs in 20-30%. So I think you had a
    wrong impression during bisecting when it booted. Just go and try booting
    a few times with a state that hung, and you will see that eventually it
    will boot. Matt had the same issue once on an Atom box and committed a fix
    to alc(4) which he thought was related to the issue, when in fact it was
    not, just because it happened to boot after that. The fix was OK
    nevertheless (just not related). :)
  • The bug is not related to hptrr or hpt27xx drivers. The messages those
    drivers give are informational and don't indicate that any such adapter
    was found. In a booting dmesg you will notice that later on they both say
    that no matching adapter was found. Also, if hpt* drivers are removed from
    the kernel config, the boot hanging will continue (just with the "Math
    emulator present" as the last message). If any messages are related to
    it, it is the IOAPIC: rman stuff (which it doesn't get to when not
    booting), but I'm not sure if something in ioapic is related to the issue.
  • The bug has nothing to do with virtio either. It started before we
    imported that.

Best regards,
Sascha

Updated by davshao almost 12 years ago

Fortunately for me, after

commit 560d12f06f3e4c73abecdac317304b94f7046cca
Date: Wed Jan 23 20:00:10 2013 +0100

the hang on boot disappeared, as in, now the Ideapad with acpi disabled boots fine. Coincidence or not, this was after I did a full
  1. make buildworld

when updating through the new m4/flex.

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:

commit 2e666a32c5a18f540aa2030ae803c3aa7e9c755a
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.

I believe this should be fixed with 902419bf6d9fd0f80afc9d07cd4b3e99d20f23ca (http://lists.dragonflybsd.org/pipermail/commits/2014-April/269851.html), so closing it. If it is still an issue, please re-open.
