These hangs seem to be I/O related. Some usual hangs: -immediately after login prompt, insert incorrect user. Notice a 2-3 minutes system hang -issue "find / | grep if". Notice system hangs at some point during the search and resumes after a long time -conduct test cases like: https://bugzilla.yoctoproject.org/tr_show_case.cgi?case_id=207 https://bugzilla.yoctoproject.org/tr_show_case.cgi?case_id=205 I believe there was a bug/discussion on this in the past and it was blamed on poor USB read/write performance. The USB stick this was tested on has 20 Mb/s write 70 Mb/s read so I believe it has decent performance. Please note that I had same issues with recent sugarbay sato-sdk images and with n450 in the past(we don't have that BSP for testing here anymore). It seems to be an overall live boot issue. 32360 1 dvhart 2013-04-18 15:31:47 +0000 I've only heard of these kinds of issues with very large live images, like lsb-sdk. I believe it is related to too little RAM. If these continue to be reported we may have to make some sort of explicit test during init. 40391 2 corneliux.stoicescu 2014-02-17 13:39:57 +0000 This is still an issue on less powerfull platforms like MinnowBoard and AtomPC(tested with genericx86 image). 40441 3 dvhart 2014-02-18 18:46:08 +0000 Also on lsb-sdk? 42038 4 corneliux.stoicescu 2014-04-01 14:12:51 +0000 Need to test this on lsb this week. 42689 5 corneliux.stoicescu 2014-04-16 07:56:13 +0000 I tested Minnowboard with a lsb-sdk image and it did not hang at all. 46814 6 richard.purdie 2014-11-06 16:27:35 +0000 It seems most boards are working except jasperforest. Assigning to Lucian to help provide more info. 47600 7 georgex.l.musat 2014-12-17 12:20:05 +0000 Had some trouble in the past with the jasperforest but it turns out to be because it is just a little more picky with the USB drives. The other images are tested regularly for live boot and there is no issue as far as I know. I think we can close this, and if there will be problems in the future open another one. 50593 8 georgex.l.musat 2015-04-29 08:27:12 +0000 Closing this.
