This message is ignorable but if you want to disable printing out of this message in the case, use this: https://github.com/Intel-BMC/openbmc/blob/intel/meta-openbmc-mods/meta-common/recipes-kernel/linux/linux-aspeed/0049-Suppress-excessive-HID-gadget-error-logs.patch Thanks, Jae > [ 682.896212] aspeed-video 1e700000.video: Timed out; first mode detect > [ 684.917892] configfs-gadget gadget: usb_ep_queue error on int > endpoint -108 > [ 685.426159] aspeed-video 1e700000.video: Timed out; first mode detect > 4, It will stop the error output when the hostOS start to bootup.[ > 739.598840] configfs-gadgetgadget: high-speed config #1: c > [ 739.629961] aspeed_vhub 1e6a0000.usb-vhub: status direction > mismatch > > Does this output make sense? > Best, > Xiuzhi > ------------------ Original ------------------ > *From: * "jae.hyun.yoo";<jae.hyun.yoo@linux.intel.com>; > *Date: * Jun 1, 2019 > *To: * "xiuzhi"<1450335857@qq.com>; "openbmc"<openbmc@lists.ozlabs.org>; > "eajames"<eajames@linux.ibm.com>; "joel"<joel@jms.id.au>; > "andrew"<andrew@aj.id.au>; > *Subject: * Re: [PATCH dev-5.1 4/4] media: aspeed: add a workaround to > fix asilicon bug (Jae Hyun Yoo) > > On 5/31/2019 4:21 AM, xiuzhi wrote: > > Hi Jae, > > I tested this patch ,it works on 1680*1050,but I found an issue: > > > > The ikvm webpage will be black screen when you reboot the host after > > switching solution between 1680*1050 and 800*600 on chrome browser (my > > chrome version is 65). > > you can reproduce it: > > 1, Set host screen solution to 1680*1050 and save it . ikvm webpage works > > 2,Set host screen solution to 800*600 and save it. ikvm webpage works > > 3,Reset host screen solution to 1680*1050 and save it, > > 4,reboot the host, > > 5, the ikvm webpage is black screen when boot to Centos GUI > > Hi Xiuzhi, > > Checked that the issue isn't related this patch.
