I've noticed that since I updated to 11.1-BETA3, a reboot from Windows into FreeBSD results in a endless reboot cycle. In order to reboot FreeBSD, I have to cold-boot. The endless reboot cycle appears to be triggered when the kernel attempts to talk to "uhub", at which point it reboots, and the cycle repeats. No kernel panics, no crash cores. The issue is not a biggie, other than the time it takes for me to power down completely, wait for capacitors to discharge completely, and then cold boot the machine. However, I thought I'd bring it to the notice of list. Cheers. -- Jonathan Chen
