OK, I renamed the driver, then rebooted and modprobed rt2800pci. This had the "nice" side-effect of kicking the other laptop off the WiFi, and I couldn't get it to associate.
rmmod -rv rt2800pci followed by modprobe -v rt2860sta got me a Kernel Panic. When the laptop rebooted, the BIOS threw up this warning: INFO [CHIPSET]: A HyperTransport Sync Flood event was detected on the last boot. Press F1 to continue booting. Rebooted, renamed rt2860sta back and re-blacklisted rt2800pci, and now my WiFi is working again. iwlist wlan0 scan: phil...@ryoko:~$ iwlist wlan0 scan wlan0 Scan completed : Cell 01 - Address: 00:14:BF:9E:46:17 Protocol:802.11g ESSID:"Stargate" Mode:Managed Channel:11 Quality:100/100 Signal level:-41 dBm Noise level:-83 dBm Encryption key:on Bit Rates:11 Mb/s IE: WPA Version 1 Group Cipher : TKIP Pairwise Ciphers (1) : TKIP Authentication Suites (1) : PSK -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/659143 Title: 64bit-only: regression: kernels >=2.6.34: rt2800pci: load firmware Error with ralink [1814:0781] -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
