Hi,
When I attempt to turn off wifi in android-2.2.1, with android-2.6.32 kernel with the TI WiLink 6.1.6.0 proprietary wlan driver, I get a kernel panic, with the message Unbalanced IRQ 257 wake disable.
What could be causing it and how can I fix it?
WARNING: at kernel/irq/manage.c:361 set_irq_wake+0x94/0x11c()
