I have the same issue with Ralink rt3690 wifi adapter.
For me the only way to get it worked without connection loss or kernel panic is
to downgrade kernel to 3.2.0-24 and compile driver provider by Ralink
(DPO_RT3290_LinuxSTA_V2600_20120508) .
In addition to default settings i turned on next settings:
HAS_BLOCK_NET_IF, HAS_KTHREAD_SUPPORT,
HAS_TSSI_ANTENNA_VARIATION, HAS_RFKILL_HW_SUPPORT
So here is activated settings in my config:
cat os/linux/config.mk | grep ^HAS | grep y
HAS_WPA_SUPPLICANT=y
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y
HAS_BLOCK_NET_IF=y
HAS_DOT11N_DRAFT3_SUPPORT=y
HAS_DOT11_N_SUPPORT=y
HAS_KTHREAD_SUPPORT=y
HAS_STATS_COUNT=y
HAS_TSSI_ANTENNA_VARIATION=y
HAS_RFKILL_HW_SUPPORT=y
HAS_OSABL_FUNC_SUPPORT=y
HAS_OSABL_OS_PCI_SUPPORT=y
HAS_OSABL_OS_USB_SUPPORT=y
HAS_OSABL_OS_AP_SUPPORT=y
HAS_OSABL_OS_STA_SUPPORT=y
HAS_LED_CONTROL_SUPPORT=y
My hardware (Asus X501U notebook):
lspci -k | tail -n 5
07:00.0 Network controller: Ralink corp. RT3290 Wireless 802.11n 1T/1R PCIe
Subsystem: Foxconn International, Inc. Device e055
Kernel driver in use: rt2860
07:00.1 Bluetooth: Ralink corp. RT3290 Bluetooth
Subsystem: Foxconn International, Inc. Device e056
My OS: Kubuntu 13.10 with kernel downgraded to 3.2.0-24 (all other kernels i
tested:
3.11.0-7, 3.5.0-40, 3.9.0-7 are not work properly with serialmonkey's/Ralink's
drivers .. this is really sad).
As far as i can see there 2 ways to fix this issue:
fix drivers from serialmonkeys project to prevent connection loss or fix Ralink
driver somehow to compile
it with modern kernel and prevent kernel panics (removing old kernel macros
from pci_main_dev.c is not enough).
