Hi, all:
I find the 2.6.28 kernel has the system hangs problem at ARMv6 SoC
platform after hundreds of reboot test, such problems do not happen at
earlier kernel version. So I wonder if there is kernel bug report for
specific kernel version?
the 2 error msgs like below:
usbcore: registered new interface driver usbfs
usbcore: registered new interface driver hub
usbcore: registered new device driver usb
ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver
