[LinuxBIOS] VIA epia-MII Hangs on reboot

[Marcel Graber]

Hi,

My EPIA-MII Board with LinuxBIos hangs sometimes on reboot.

The Shutdown Process goes completly down,  the Screen is flickering.

-          I've tried the different reboot options in Kernel, but I get
the same situation.

-          I removed again the viafb Device

-          I tried different acpi / apm Options

-          I tried with / without noapic Kernel-Option

I don't know where to search now. Is this a Problem in Hardware, Bios or
Kernel?

My Configuration:

-          Via EPIA-MII

-          Kernel 2.6.20

-          LinuxBios / Filo (Boot from CF Card)

Thanks for Input,

marcel

It should work out of the box without any options (ACPI needs to be
enabled I think)

What MII is it? 6000? 10000?

Maybe a kernel issue? I did not try this with 2.6.20... I think the
latest I tried was the 2.6.18 SUSE patched kernel.

Hi Stefan,

It's a MII 6000EG Board

Perhaps, the SUSE Kernel has a patch (in reboot_fixups.c?)?
I've build the Kernel from Kernel.org (with viafb and bootsplash patch)

What's the EG? Mine is a 6000E

EG is equivalent to E just RoHS-compliant.

I was also unable to reboot reliably with my EPIA-MII 6000E board
using vanilla 2.6.17-2.6.18 kernels with and without viafb.

With the Fedora Rescue System, everything is , but with the Debian initrd / kernel I have also the reboot problem.

Ok, I've found a solution:

setpci -s 0:11.0 4f.b=9

not very nice, but it works....

Does reboot work with that?

Yes, I set this command in my /sbin/reboot
