In some environments, like my home, my ral WiFi device works like a charm. No problems whatsoever. But in some environments, like my office, it causes a massive interrupt storm (in the order of 70000 interrupts per second) to occur. I have the following device in my laptop (output of pciconf -l -v): ral0@pci0:5:9:0: class=0x028000 card=0xb8331462 chip=0x03021814 rev=0x00 hdr=0x00 vendor = 'Ralink Technology, Corp' device = 'RT2525 2.4GHz transceiver + RT2560 MAC/BBP wireless a/b' class = network In my office environment, the device does not detect any networks at all. My colleague's laptop, which has a recent Intel chipset-based WiFi card (and also runs the same version of FreeBSD), has no problems with the environment, and in fact it detects more than ten networks. Stopping the interface with "/etc/rc.d/netif stop ral0" causes the interrupt storm to stop. Starting the interface again (it's configured for DHCP and WPA by the way in /etc/rc.conf) causes the interrupt storm to resume as before. But even if the device is not up, it produces around 30 interrupts per second. No idea is that's normal or not, though. Fix: I'm not sure what the problem is, let alone a solution. How-To-Repeat: I don't know how other people could reproduce the problem. I know how to reproduce it in my two described environments, though, so if anyone wants me to test anything (custom patches, etc are no problem) in either environment, that's certainly possible.
Hi, For two years I have been successfully using an Ralink Wireless Ethernet card with a Belkin F1PI241EGau wireless router under FreeBSD 6. After upgrading to FreeBSD 7 RC1 the card doesn't reliably connect to the router at bootup. Perhaps the problem is related to this PR? I am not sure how to diagnose an "interrupt storm". There is nothing relevant in /var/log/messages. Rebooting (sometimes multiple times) fixes the problem. As you can see in the following example, simply restarting ral0 is not sufficient. I have not seen this problem when booting into Win2K.

To follow-up my previous message, I am seeing the following in /var/log/messages: smbd[1503]: read_data: read failure for 4 bytes to client 192.168.0.2.

Hi, I can confirm this bug running 7.0-RC2-p1 with a Conceptronic C54Ri =20 Revision 2.0 pci card. The card works fine with Windows XP and Linux. =20 Restarting the interface or rebooting the pc _never_ fixed the problem =20 over here. The manufacturer tells on his website (conceptronic.net) =20 which card version is using which chipset: C54RC and C54Ri: Ralink RT2560F + RT2525L C54RC and C54Ri Version 2.0: Ralink RT2501 Turbo Chipset =3D=3D Ralink =20 RT2561T +RT2527L C54RC version 2.0 without ROHS logo: RT2560F + RT2525L C54RC version 2.0 with ROHS logo: RT2561T +RT2527L Pciconf output seems to be wrong...
