I have only seen this with the wireless problem already noted. Can you see if blacklisting the wireless driver fixes the problem?
Hmmm. What wireless problem?
echo blacklist wl12xx_sdio > /etc/modeprobe.d/blacklist-wireless.conf reboot
The IGEPv2 doesn't use wl12xx; it uses the libertas (it's got a Marvell 88w8686 onboard).
Just to be clear, wifi works fine on this device, out of the box.
Isn't there a way to trigger a backtrace or dump of the hung kworker task?
PS: I just boot-tested the latest 1003 kernel and it's working fine; in fact, I now get a flashing green light when the box is on, whereas before I used to get a dead led. The U-Boot issues I pointed out earlier are still there, though.
It seems that this issue was fixed with 1003 as soon as we disabled cpu_freq for both Omap 3 and Omap 4. Didn't confirm, but that would be the main change regarding Omap 3.
For Omap 4 the wlan driver was also causing similar issues.
