Edimax rt73 based usb wireless stick locks pc with 2.6.26 kernel

Ratusutar · 2008-09-04 11:42:48

I'm new around here so if wrong forum or anything else, apologies.
This is more a kernel issue rather than Archlinux as, just coming from Debian Sid, I had problems with this stick since kernel 2.6.24

Bus 002 Device 005: ID 148f:2573 Ralink Technology, Corp.
idVendor 0x148f Ralink Technology, Corp.

Workaround: (requires other network access to get rt73 legacy driver from http://rt2x00.serialmonkey.com/wiki/index.php/Downloads )

Remove stick and power off/on pc.
Blacklist kernel ralink modules via rc.conf (!rt2500usb !rt2x00lib !rt2x00usb !rt73usb)
Build legacy driver
modprobe rt73

I have the same stick (148f:2573) and no problems whatsoever with rt73usb.
I did however blacklist the rt2500usb module with 'blacklist rt2500usb' in /etc/modules.d/myblacklist (together with a few filesystem modules I don't want to get probed by pmount); blacklisting in rc.conf only helps during the initial boot.

Prior to the .26 kernel issue (and Archlinux) for me it performance that was seriously lacking (ran like a 56k modem) with kernel rt73usb module. Next kernel update I'll give the rt73usb a try.

Thanks

About the performance, well, I didn't test real-world wireless usage with the stick yet. Only verified that the drivers were ok and that it could see some networks.

under ubuntu, the rt73usb kernel driver was unsuable for me, it froze every 5 minutes, requiering either a network restart, or a complete system reboot. rt73 worked ok, but quite gruesome to automate.

under arch, the rt73usb works much better, but still i get the ocassional network lockup, which gets fixed by restarting the network (/etc/rc.d/net-auto restart).

i built rt73 legacy but no matter what i did, the firmware was claimed missing, even if it actually was there (/lib/firmware/rt73.bin exists)

i wonder, why the need to blacklist rt2500usb? does the module conflict with rt73usb?

No, it doesn't. I tried the stick again and to be honest, I don't really know why I had blacklisted it. Only seems to be useless and does no harm.
