The most recent 2.6.31 built via Jeremy's Git Repos loads as vanilla on
top of Ubuntu 9.04 Server.

OK. What about the boot _without_ Xen?

Boris,

Let me specific. Please boot up without Xen, the kernel
that was built on Wed Sep 9 16:02:46 MSD 2009(2.6.31-rc8), and use
the serial console.

Using the vanilla kernel does not help me. I need to understand what is 
different when you boot 2.6.31-rc8 under Xen and without Xen. Comparing
it to a 2.6.31 is not helping.

[-- Attachment #1.1: Type: text/plain, Size: 1497 bytes --]

Out of ideas how to setup serial console on Ubuntu 9.04 for vanilla kernel.

title vmlinuz-2.6.31-rc8 Serial / Ubuntu 9.04 Jaunty (kernel 2.6.31-rc8)
    kernel  /vmlinuz-2.6.31-rc8  root=/dev/sdc2  ro com1=9600,8n1 console=com1 console=ttyS0 
    initrd  /initrd-2.6.31-rc8.img

doesn't work.

Googling provides outdated information. (RH 7.2, Suse 10.2)
It just crashes grub.

Boris.

serial console setup for normal Linux kernel (non-xen):

vmlinuz root=whatever ro console=tty0 console=ttyS0,9600n8

That should work if it's a normal onboard serial port.

If that doesn't work then try with "console=ttyS0,9600", 
which enables flow control.

Re: Attempt to load 2.6.31-rc8 under Xen 3.4.1 on top of Ubuntu 9.04 Server ( JF's 2.6.31 loaded as vanilla)

[Boris Derzhavets]

[-- Attachment #1.1: Type: text/plain, Size: 3382 bytes --]

Pasi,

I've tried :-

title vmlinuz-2.6.31-rc8 Serial / Ubuntu 9.04 Jaunty (kernel 2.6.31-rc8)
    kernel  /vmlinuz-2.6.31-rc8  root=/dev/sdc2  ro console=tty0 console=ttyS0,9600
    initrd  /initrd-2.6.31-rc8.img

and

title vmlinuz-2.6.31-rc8 Serial / Ubuntu 9.04 Jaunty (kernel 2.6.31-rc8)
    kernel  /vmlinuz-2.6.31-rc8  root=/dev/sdc2  ro console=tty0 console=ttyS0,9600n8
    initrd  /initrd-2.6.31-rc8.img

Both options send output to real console and hangs at the point as under 
Xen.

Boris.
P.S  Null modem connection is OK . I verified for Xen Serial Grub Entry.

Can you still ping the machine after that? Does the VGA screen show anything?
Can you SSH in it?

Booting up stops before DHCP request.
Obviously, no

Yes , usual console output.
It hangs at the same point as under Xen.

Please post "dmesg | grep ttyS" output from baremetal kernel (non-xen). 

Is the serial port onboard (integrated into the motherboard)? 
or pci addon card?

For 2.6.31 loaded as vanilla :-

Linux ServerJaunty 2.6.31 #3 SMP Fri Sep 11 02:19:43 CDT 2009 x86_64 GNU/Linux
root@ServerJaunty:~# dmesg | grep ttyS
[   13.811223] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[   13.903839] 00:0b: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A

It's integrated on board (ASUS P5Q-E) and connected via small cable to
output socket.

Please post "dmesg | grep ttyS" output from baremetal kernel (non-xen). 

Is the serial port onboard (integrated into the motherboard)? 
or pci addon card?

If you mean as  Xen Dom0 enabled under Xen 3.4.1, then
2.6.31 works fine on F11,F12,Ubuntu 9.04 Server.

Well you could always use "dmesg > dmesg.txt" .. 

No need to setup serial console, unless the kernel crashes..

If it crashes, try to use only "console=ttyS0,blah", ie. drop "console=tty0"

Vanilla 2.6.31-rc8 crashes.

Dropped, still no luck.

Well you could always use "dmesg > dmesg.txt" .. 

No need to setup serial console, unless the kernel crashes..

If it crashes, try to use only "console=ttyS0,blah", ie. drop "console=tty0"

Can you paste again the grub entry for Xen with serial console?

That should definitely work for baremetal kernel. Does your kernel have
serial support built-in? 

Are you sure your serial port settings on the other computer are ok? 
Try using "minicom" and playing with the different flow control
settings.. (no flow control / hardware flowcontrol / xon,xoff)

Re: Attempt to load 2.6.31-rc8 under Xen 3.4.1 on top of Ubuntu 9.04 Server ( JF's 2.6.31 loaded as vanilla)

OK, Pasi
I tuned minicom , now it's accepting data from Xen Serial Console just nice..
Still nothing from vanilla kernel 2.6.31-rc8. 
I believe kernel has been built improperly. It doesn't send data to /dev/ttyS0.

Boris.

kernel /vmlinuz-2.6.31-rc8 ro root=/dev/sdc2 console=ttyS0,9600

That should definitely work for baremetal kernel. Does your kernel have
serial support built-in? 

Are you sure your serial port settings on the other computer are ok? 
Try using "minicom" and playing with the different flow control
settings.. (no flow control / hardware flowcontrol / xon,xoff)

Re: Attempt to load 2.6.31-rc8 under Xen 3.4.1 on top of Ubuntu 9.04 Server ( JF's 2.6.31 loaded as vanilla)

[Boris Derzhavets]

[-- Attachment #1.1: Type: text/plain, Size: 5553 bytes --]

Attempt to bisect to rc8:-


git bisect start
git bisect bad fc26d1b48781ec414899947d227f533c3e3010b9
git bisect good 04106d0439e81780a48db38f5c0ee6c15a1d2f04

doesn't allow me restore .config for Xen Dom0 support.

I am missing something trying to bisect.

Boris.
