Hi, Firstly, please cc me into any any replies - I'm not subscribed. In 2.6.25 kernels, my wireless LAN dies after even the smallest amount of network activity. The following screen cut shows what I typically see: [chris:~]$ uname -a Linux laptop 2.6.25-rc2 #10 PREEMPT Sat Feb 16 09:53:04 UTC 2008 i686 GNU/Linux [chris:~]$ ping 192.168.1.1 PING 192.168.1.1 (192.168.1.1) from 192.168.1.30 : 56(84) bytes of data. 64 bytes from 192.168.1.1: icmp_seq=0 ttl=255 time=9.837 msec 64 bytes from 192.168.1.1: icmp_seq=1 ttl=255 time=3.148 msec 64 bytes from 192.168.1.1: icmp_seq=2 ttl=255 time=2.205 msec ^C --- 192.168.1.1 ping statistics --- 9 packets transmitted, 3 packets received, 66% packet loss round-trip min/avg/max/mdev = 2.205/5.063/9.837/3.397 ms [chris:~]$ dmesg | tail NET: Unregistered protocol family 23 parport_pc 00:0f: disabled ACPI: PCI interrupt for device 0000:02:00.0 disabled ACPI: PCI Interrupt 0000:01:00.0[A] -> Link [LNKA] -> GSI 11 (level, low) -> IRQ 11 [drm] Initialized radeon 1.28.0 20060524 on minor 0 agpgart: Found an AGP 2.0 compliant device at 0000:00:00.0. agpgart: Putting AGP V2 device at 0000:00:00.0 into 2x mode agpgart: Putting AGP V2 device at 0000:01:00.0 into 2x mode [drm] Setting GART location based on old memory map [drm] writeback test succeeded in 1 usecs [chris:~]$ As you can see, after a few packets, the ping application hangs and after that point, all network accesses fail. There are no error messages written to the logs when the network dies. I can restart the network by simply unloading and reloading the driver. This hang does not occur with a different wireless card that uses the rtl8180 driver. My config and the output from dmesg (after reloading the driver) are attached. I have Ralink debugfs enabled so can provide any additional diagnostics that may be helpful from that source. (I should perhaps add that I am sure that this is not the same problem I reported tthrough bugzilla (bug 9860) a few weeks ago, which it seems was a problem with my AP/router. Since resetting my AP/Router, I can reboot to 2.6.24.2 and the wireless network works reliably with the same hardware.) The hardware is a Belkin F5D7010 802.11g Notebook card communicating with a Draytek Vigor 2600 802.11b combined AP/Router/Broadband Modem. I will be more than happy to provide additional diagnostics, but please bear in mind that I am not a git user, so cannot do bisects. I am, however, perfectly capable of applying or reverting patches, rebuilding and re-testing, so I am quite happy to do that. Thanks in advance. Chris
