Hello,
Thank you for your advice. I applyed appropriate patch and one problem disappeared. But the second issue is still present.
I have two Ethernet NIC with similar chipsets and I would like use first adapter with RTnet and second onet with standard Linux networking. But my system hangs a few seconds after bringing up both interfaces.
First a few details about my hardware and software:
Linux Fedora Core 1 with 2.4.22 kernel
RTAI 3.0 r 4
RTnet 0.6.2 with patch
two NIC compatible with RTL8139 chipset
(I'll give more info about NICs further)Following sequence of commnads makes my system not respond:
# At boot time init automatically brings up networking. # Hence I need bring it down. service network stop # Removing Linux NIC driver installed at boot time. rmmod 8139too
cd /usr/local/rtai/modules
# Loading required RTAI modules. insmod rtai_hal.o insmod rtai_ksched.o insmod rtai_sem.o
cd /usr/local/rtnet/modules
# Loading required RTnet module. insmod rtnet.o
# Installing RT driver for first NIC. insmod 8139too-rt.o cards=1
# Installing casual driver for second NIC. insmod 8139too
# Bringing up Linux network interface. ifconfig eth0 up 192.168.19.12
cd /usr/local/rtnet/sbin
# Bringing up RTnet network interface. ./rtifconfig rteth0 up 149.156.105.15 netmask 255.255.255.0
A few second after issuing last command system hung (no reaction to any keyboard action including Num_Lock and Ctrl+Alt+Del). The time between last command and crash varies from almost instant to several seconds.
If I load both drivers without bringing up any interfaces system works properly.
If I load both drivers and bring up only ONE interface (RT xor Linux) system works properly, too.
But after loading and bringing up BOTH interfaces (RT and Linux) the problem arises.
Computer behaves in the same manner with newer version of RTnet - 0.7.0.
And one more question. Maybe it makes little sense but I tryed to use both NICs with RTnet. I loaded 8139too-rt.o driver for both of them. But it's possible to bring up only one interface (say rteth0). When I issue 'rtifconfig' command against second one (rteth1) I get 'Device or resource busy' message. Is there a way to overcome this?
And this is output of handful of commands issued in my system:
lsmod | grep 8139
8139too 18120 0 (unused) 8139too-rt 10412 0 (unused) rtnet 68680 0 [8139too 8139too-rt] rtai_sem 20384 0 [8139too-rt rtnet] rtai_ksched 48057 0 [8139too-rt rtnet rtai_sem] rtai_hal 13868 1 [8139too-rt rtnet rtai_sem rtai_ksched] mii 3604 0 [8139too]
The list above reveals that '8139too' driver (like 8139too-rt) use 'rtnet' module.
Should it?
