I have a new laptop that I am trying to work with Xen 3.0.
The network card is a Broadcom 4400 10/100BaseT.
Normally loading the b44 module gives this:
Apr 28 20:07:53 ipanema kernel: [4294683.185000] b44.c:v0.97 (Nov 30, 2005)
Apr 28 20:07:53 ipanema kernel: [4294683.185000] ACPI: PCI Interrupt
0000:03:00.0[A] -> GSI 17 (level, low) -> IRQ 177
Apr 28 20:07:53 ipanema kernel: [4294683.189000] eth0: Broadcom 4400
10/100BaseT Ethernet 00:14:22:f2:57:36
(under an Ubuntu kernel - 2.6.15-21-686 #1 SMP PREEMPT)
Works similarly under a vanilla 2.6.16.
When running a Xen patched 2.6.16 (as per
https://wiki.ubuntu.com/XenVirtualMachine/XenOnUbuntuDapper) or on the Xen
live CD, I get:
Apr 27 00:28:31 ipanema kernel: [ 20.038669] b44.c:v0.97 (Nov 30, 2005)
Apr 27 00:28:31 ipanema kernel: [ 20.038700] ACPI: PCI Interrupt
0000:03:00.0[A] -> GSI 17 (level, low) -> IRQ 17
Apr 27 00:28:31 ipanema kernel: [ 20.038710] b44: No usable DMA
configuration, aborting.
Apr 27 00:28:31 ipanema kernel: [ 20.040248] ACPI: PCI interrupt for
device 0000:03:00.0 disabled
Apr 27 00:28:31 ipanema kernel: [ 20.040251] b44: probe of 0000:03:00.0
failed with error -5
Am I doing something wrong?
The first difference here is that ACPI allocates IRQ 17 instead of IRQ
177. Hope that rings bells for somebody :-)
This is the relevant output of lspci -vvvv while it''s running under
2.6.16:

Laptop is Dell 9400 Core Duo T2600 2Gb Ram , SATA 100Gb
The ultimate aim is to use the Intel VT extensions to run unmodified OSes
underneath, but that''s not that useful without networking.
Other hints of problems: noticable graphics corruption under framebuffer
console while running xen kernel.
cheers,
Woody
PS: side question, is it possible to present a DomU unmodified OS with
full / exclusive access to the Video card. (PCI-X nVidia Go 7800),
obviously giving no video to Dom0.

Re: [Xen-users] b44 module fails to work with xen patched kernel
Does anyone know if there is any work being done on this? Is there anything I can do to help move it along? I''m in exactly the same position. I''ve got a Dell E1705 with same hardware config as Woody (Same as 9400, just branded different) RE: "Bugzilla bug 187929: b44 module is not compiled into kernel-xen0" This bug hasn''t been updated since April 2006 when the b44 module was disabled in kernel config due to "unknown symbol dma_get_cache_alignment" I''ve had this laptop for several months now, hoping Xen development would catch up to the new hardware. I''m running FC5 but can''t use VT extensions in the Centrino Duo to run the xen kernels. I''ll be updating the bug with my data, but I''m not holding my breath. Apparently there are too few of us using this driver, or too few reporting it. --Cal Webster On Fri, 2006-04-28 at 09:48, Woody wrote:> I have a new laptop that I am trying to work with Xen 3.0. > > The network card is a Broadcom 4400 10/100BaseT. > > Normally loading the b44 module gives this: > > Apr 28 20:07:53 ipanema kernel: [4294683.185000] b44.c:v0.97 (Nov 30, 2005) > Apr 28 20:07:53 ipanema kernel: [4294683.185000] ACPI: PCI Interrupt > 0000:03:00.0[A] -> GSI 17 (level, low) -> IRQ 177 > Apr 28 20:07:53 ipanema kernel: [4294683.189000] eth0: Broadcom 4400 > 10/100BaseT Ethernet 00:14:22:f2:57:36 > > (under an Ubuntu kernel - 2.6.15-21-686 #1 SMP PREEMPT) > Works similarly under a vanilla 2.6.16. > > When running a Xen patched 2.6.16 (as per > https://wiki.ubuntu.com/XenVirtualMachine/XenOnUbuntuDapper) or on the Xen > live CD, I get: > > Apr 27 00:28:31 ipanema kernel: [ 20.038669] b44.c:v0.97 (Nov 30, 2005) > Apr 27 00:28:31 ipanema kernel: [ 20.038700] ACPI: PCI Interrupt > 0000:03:00.0[A] -> GSI 17 (level, low) -> IRQ 17 > Apr 27 00:28:31 ipanema kernel: [ 20.038710] b44: No usable DMA > configuration, aborting. > Apr 27 00:28:31 ipanema kernel: [ 20.040248] ACPI: PCI interrupt for > device 0000:03:00.0 disabled > Apr 27 00:28:31 ipanema kernel: [ 20.040251] b44: probe of 0000:03:00.0 > failed with error -5 > > Am I doing something wrong? > > The first difference here is that ACPI allocates IRQ 17 instead of IRQ > 177.

Re: [Xen-users] b44 module fails to work with xen patched kernel
Did you have to rebuild your kernel(s)? If there''s any hope at all, that''ll be my next ToDo. I was hoping to be able to use the stock FC kernels, but I really need Xen now for my work. --Cal Webster On Wed, 2006-09-06 at 06:38, Marcin Owsiany wrote:> On Wed, Sep 06, 2006 at 12:22:28AM -0400, Calvin Webster wrote: > > Is there anything I can do to help move it along? > > > > I''m in exactly the same position. > > > > I''ve got a Dell E1705 with same hardware config as Woody (Same as 9400, > > just branded different) > > > > RE: "Bugzilla bug 187929: b44 module is not compiled into kernel-xen0" > > > > This bug hasn''t been updated since April 2006 when the b44 module was > > disabled in kernel config due to "unknown symbol > > dma_get_cache_alignment" > > > > I''ve had this laptop for several months now, hoping Xen development > > would catch up to the new hardware.
