We currently use the FW-6490 made in Lanner. The following is spec.
---------------------------------------------------
Model Name: FW-6490F
HDD: CF 4G
NIC: Intel 82573L x 2 , 82541Gi x 2
Mainboard chip sets: VIA CN700 + VT8251
OS : Fedora4(kernel?2.6.11-1.1369_FC4)
----------------------------------------------------
We installed the e1000e-0.4.1.7 for use of Intel 82573L NIC.
Later, those equipment is working order, but they occur the unspecified hang
or kernel panic.
We tried to find the cause of this problem in various ways.
But we couldn’t find a clear answer and the content was confirmed as blow.
The content was added in e1000e-1.1.2 as follow.
--------------------------------------------------------------------------------------------
TROUBLESHOOTING: Some systems have trouble supporting MSI and/or MSI-X
interrupts. If you believe your system needs to disable this style of
interrupt, the driver can be built and installed with the command:
# make CFLAGS_EXTRA=-DDISABLE_PCI_MSI install
Normally the driver will generate an interrupt every two seconds, so if
you can see that you're no longer getting interrupts in
cat /proc/interrupts for the ethX e1000e device, then this workaround
may be necessary.
---------------------------------------------------------------------------------------------
In addition, we confirmed that the option didn’t exist related to MSI in
kernel 2.6.11-1.1369_FC4.
In case of Fedora8, the option related to MSI is contained as follow.
--------------------------------------------------------
cat /boot/config-2.6.23.1-42.fc8 | grep MSI
CONFIG_ARCH_SUPPORTS_MSI=y
CONFIG_PCI_MSI=y
CONFIG_MSI_LAPTOP=m
-------------------------------------------------------
We confirmed that Intel 82573L NIC which we use now didn’t support the MSI,
too.
-----------------------------------------------------------------------------
Q1: If we don't apply the added TROUBLESHOOTING option to e10003-1.1.2, what
problem has arise?
Q2: If I use the Intel 82573L in kernel 2.6.11-1.1369_FC4 which can’t set a
option related to MSI, can it occur the kernel panic or hang caused by the
use of e1000e-0.4.1.7?
