FOG - boot to FOS - rcu_sched self-detected stall on CPU

[abos_systemax]

@Tom-Elliott I don’t know why it boots to bz32… it does apparently…
I assumed that it used bzImage for UEFI because UEFI doesn’t really support x32?

however, I retrieved the boot command from the boot.php and forced the boot.php to present it to this machine with bzImage instead of bzImage32 and now it apparently seems to work…

Somehow it doesn’t give it’s archtype correctly?

===

If I drop to Shelland check the buildarch, then it displays i386.
Could this be my DHCP server that is confused?

This is my DHCP config:

option space PXE;
option PXE.mtftp-ip    code 1 = ip-address;
option PXE.mtftp-cport code 2 = unsigned integer 16;
option PXE.mtftp-sport code 3 = unsigned integer 16;
option PXE.mtftp-tmout code 4 = unsigned integer 8;
option PXE.mtftp-delay code 5 = unsigned integer 8;
option arch code 93 = unsigned integer 16; # RFC4578

authoritative;
allow unknown-clients;
option broadcast-address 192.168.71.255;
option subnet-mask 255.255.252.0;
option routers 192.168.68.1;
ddns-update-style none;
option domain-name "local";
option domain-name-servers 192.168.68.11, 8.8.8.8;
default-lease-time 600;
max-lease-time 7200;
log-facility local7;

# LAN
subnet 192.168.68.0 netmask 255.255.252.0 {
	max-lease-time 14400;
	default-lease-time 14400;
	allow unknown-clients;
	next-server 192.168.68.13;
	range 192.168.68.30 192.168.71.200;
	}

class "pxeclient" {
    match if substring (option vendor-class-identifier, 0, 9) = "PXEClient";

    if substring (option vendor-class-identifier, 15, 5) = "00000" {
        # BIOS client 
        filename "undionly.kpxe";
    }
    elsif substring (option vendor-class-identifier, 15, 5) = "00006" {
        # EFI client 32 bit
        filename   "ipxe32.efi";
    }
    else {
        # default to EFI 64 bit
        filename   "ipxe.efi";
    }
   }

The config states the following:

Chip: undionly
filename: undionly.kpxe
buildarch: i386
platform: pcbios

@abos_systemax When it shows the loading of the init, is it also changing the number?

bzImage32 with init_32.xz

bzImage with init.xz

[abos_systemax]

@Tom-Elliott I will get back to you on that, Now that i Have a workaround I first need to finish the current job before I can test any further

edit
== Yes, it changes both accordingly

[Tom Elliott]

@abos_systemax can you get a pic or video of the screen displaying as it’s booting through pxe? Basically start up through to trying to load into fog.

[abos_systemax]

The issue only appears on known hosts apparently. We have no issues on hosts that fog doesn’t know somehow.
I’m still trying to investigate why the arch isn’t parsed correctly on this device… will post as soon as I find an answer

@abos_systemax said in FOG - boot to FOS - rcu_sched self-detected stall on CPU:

I assumed that it used bzImage for UEFI because UEFI doesn’t really support x32?

It does. There aren’t a lot of UEFI systems that are 32 bit, but they are out there.

Are you using the boot files that come with fog and are you serving them from the FOG Server? Could these files be obsolete or are you shuffling things around? I only ask because the filename you give in your dhcpd.conf file is not where that file actually is located on a 1.3.0 RC fog server by default.

At any rate, if you’re serving these boot files from a FOG server on 1.3.0 RC, the PXEClient:Arch:00006 filename should instead be: filename "i386-efi/ipxe.efi";

Also, if you wanted, you could simply replace all of your classes in your dhcpd.conf file with these (standard FOG isc-dhcp classes):

    class "UEFI-32-1" {
        match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00006";
        filename "i386-efi/ipxe.efi";
    }
    class "UEFI-32-2" {
        match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00002";
        filename "i386-efi/ipxe.efi";
    }
    class "UEFI-64-1" {
        match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00007";
        filename "ipxe.efi";
    }
    class "UEFI-64-2" {
        match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00008";
        filename "ipxe.efi";
    }
    class "UEFI-64-3" {
        match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00009";
        filename "ipxe.efi";
    }
    class "Legacy" {
        match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00000";
        filename "undionly.kkpxe";
    }

    class "SURFACE-Pro-4" {
    match if substring(option vendor-class-identifier, 0, 32) = "PXEClient:Arch:00007:UNDI:003016";
    filename "ipxe7156.efi";
    }

    class "Apple-Intel-Netboot" {
        match if substring (option vendor-class-identifier, 0, 14) = "AAPLBSDPC/i386";
        option dhcp-parameter-request-list 1,3,17,43,60;
        if (option dhcp-message-type = 8) {
            option vendor-class-identifier "AAPLBSDPC";
            if (substring(option vendor-encapsulated-options, 0, 3) = 01:01:01) {
                # BSDP List
                option vendor-encapsulated-options 01:01:01:04:02:80:00:07:04:81:00:05:2a:09:0D:81:00:05:2a:08:69:50:58:45:2d:46:4f:47;
            }
            elsif (substring(option vendor-encapsulated-options, 0, 3) = 01:01:02) {
                # BSDP Select
                option vendor-encapsulated-options 01:01:02:08:04:81:00:05:2a:82:0a:4e:65:74:42:6f:6f:74:30:30:31;
