2. Following is the output for "lshal" mentioning the Ethernet details on Fedora 7:
udi = '/org/freedesktop/Hal/devices/pci_14e4_1713'
info.bus = 'pci' (string)
info.linux.driver = 'tg3' (string)
info.parent = '/org/freedesktop/Hal/devices/pci_8086_2843' (string)
info.product = 'NetLink BCM5906M Fast Ethernet PCI Express' (string)
info.subsystem = 'pci' (string)
info.udi = '/org/freedesktop/Hal/devices/pci_14e4_1713' (string)
info.vendor = 'Broadcom Corporation' (string)
linux.hotplug_type = 2 (0x2) (int)
linux.subsystem = 'pci' (string)
linux.sysfs_path = '/sys/devices/pci0000:00/0000:00:1c.2/0000:18:00.0' (string)
pci.device_class = 2 (0x2) (int)
pci.device_protocol = 0 (0x0) (int)
pci.device_subclass = 0 (0x0) (int)
pci.linux.sysfs_path = '/sys/devices/pci0000:00/0000:00:1c.2/0000:18:00.0'
pci.product = 'NetLink BCM5906M Fast Ethernet PCI Express' (string)
pci.product_id = 5907 (0x1713) (int)
pci.subsys_product_id = 12480 (0x30c0) (int)
pci.subsys_vendor = 'Hewlett-Packard Company' (string)
pci.subsys_vendor_id = 4156 (0x103c) (int)

This is on the HP nc6710s.
Adding HP to the bug so that they can assist.
RHEL5.1 will contain the lastest tg3 driver upstream. If it works on F7, there
is an excellent chance it will work on 5.1 as well. Please test kernels here:
and report back whether the networking is working or not. Thanks!

When tested with the new kernel downloaded from the Link mentioned above.
The system gives Kernel Panic while booting up, just after starting udev.
Can you copy the details of the panic here (like captured with a serial
smohan from Pune office mentioned that he has the hardware available to
facilitate the testing effort. Hence, if this bug gets included, we will help to
test this bug.

Kernel panic screen shot
As the serial console and the loop back cable is not available, the screen-shot
for the same has been attached.
Network controller is still not working on RHEL5 Update1 beta.
When tried with RHEL5 Update1 Beta, the installation went smooth in graphical
mode. But after installation, on rebooting the system, the kernel paniced.
Thus, to check the network controller functionality, we tried installing the OS
using NFS method.
On selecting NFS, OS was unable to load the appropriate Network driver.
Then on selecting the Broadcom 'tg3' driver from the displayed list, the
following message was displayed: "No device found"
Setting the exception flag for RHEL 5.1.
This feature, along with BZ 245143, alre required to support a 15K laptop
Brian apparently has this laptop. The panic in comment #11 seems to look like a
sound issue. Are you working on that one, Brian? Apparently the kernels in
comment #3 seem to cause this panic.
I did not see any panic on this system with any of the kernels I have tested,
but I will test the kernel in Comment #3 and report back my findings.
Is the modem disabled on your laptop? I'm wondering is the softmodem driver (a
binary blob) is causing the panic in comment #11, or another audio stream.

Brian has confirmed this patch will resolve the issue of the 5906M not working.
You can download this test kernel from http://people.redhat.com/dzickus/el5
