I have try to deactivate my wifi card I put "blacklist rt2500" in the file "/etc/modprobe.d/blacklist" and now everything seems to be OK.
Here is my network interfaces (lshw) ------------------------- *-network:0 UNCLAIMED description: Network controller product: RT2500 802.11g Cardbus/mini-PCI vendor: RaLink physical id: 9 bus info: [EMAIL PROTECTED]:09.0 version: 01 width: 32 bits clock: 33MHz capabilities: bus_master cap_list configuration: latency=64 resources: iomemory:fa700000-fa701fff irq:11 *-network:1 description: Ethernet interface product: 88E8001 Gigabit Ethernet Controller vendor: Marvell Technology Group Ltd. physical id: a bus info: [EMAIL PROTECTED]:0a.0 logical name: eth0 version: 13 serial: 00:11:2f:dc:02:1c width: 32 bits clock: 66MHz capabilities: bus_master cap_list ethernet physical configuration: broadcast=yes driver=skge driverversion=1.9 firmware=N/A ip=82.245.248.140 latency=64 maxlatency=31 mingnt=23 multicast=yes resources: iomemory:fa900000-fa903fff ioport:a400-a4ff irq:18 *-network:2 description: Ethernet interface product: DGE-528T Gigabit Ethernet Adapter vendor: D-Link System Inc physical id: c bus info: [EMAIL PROTECTED]:0c.0 logical name: eth2 version: 10 serial: 00:11:95:65:f1:ae width: 32 bits clock: 66MHz capabilities: bus_master cap_list ethernet physical configuration: broadcast=yes driver=r8169 driverversion=2.2LK ip=192.168.0.1 latency=64 maxlatency=64 mingnt=32 multicast=yes resources: ioport:a800-a8ff iomemory:fab00000-fab000ff irq:18 ------------------------- NB : I NEVER use my wifi card. The second interface is connected to internet (dhcp) and the third interface is connected to my private network (static IP) As I see I/O on my wifi card with the command "ifconfig" even it is not configured, I try to desactivate it and all works great now ! -- [Feisty] Network go down and system freeze randomly https://bugs.launchpad.net/bugs/102748 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
