When I first plug power into my BBGW, everything works great. But if I issue a "reboot" or "shutdown -r now" command, when the device boots back up I have no wifi.
*Anyone else having problems with wifi not working when doing a "warm" reboot? Is this a known problem, or is there a known workaround?* I've diff'd the output of the serial console when it works and when it doesn't, and I only see 1 line difference at the very start of the boot process. When it works: DRAM: 512 MiB Reset Source: Power-on reset has occurred. MMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1 When it doesn't work: DRAM: 512 MiB Reset Source: Global warm SW reset has occurred. Reset Source: Power-on reset has occurred. MMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1 When it doesn't work, I get this message logged in dmesg every few seconds after the boot has finished: [ 612.676285] wlcore: ERROR firmware boot failed despite 3 retries [ 620.458410] wlcore: ERROR timeout waiting for the hardware to complete initialization [ 622.558761] wlcore: ERROR timeout waiting for the hardware to complete initialization [ 624.634344] wlcore: ERROR timeout waiting for the hardware to complete initialization The only other thing I've noticed is a 20-line error message and backtrace logged to /var/log/messages.
