It is my suspicion that the change occurred at switch to 4.18; but only because of timeline, and Walter (WXL) discussion providing a link to a possible cause that was introduced shortly after what I recall as being my last successful test on those machines (755, dc7700 anyway)
I'm new to testing, and hadn't found the QA-tracker when I started testing 18.10, so my successful tests on those boxes aren't recorded which right now is a pain, for which I'm sorry. I requested on IRC to see if anyone knows where I can download a 4.17 kernel x86 ISO (either xubuntu or lubuntu) when this bug was reported, but it was ~3 weeks ago (3-4?) when last tested successfully on dell 755 & hp dc7700. (I have no idea if or when it was last tested on x201 (I rarely think of it) If older images are available, I'll happily test them (any 4.17 x86 image is what I wanted to start testing on to confirm wxl's theory) --- changed to CONFIRMED as I can't run ubuntu-bug -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1795092 Title: xubuntu 18.10 daily image (x86) fails to boot - initramfs Status in linux package in Ubuntu: Confirmed Status in linux source package in Cosmic: Confirmed Bug description: x86 daily image (32bit) XUBUNTU 18.10 - booted & ran fine on dell latitude d610 - booted & ran fine on ibm thinkpad t43 fails on - hp dc7700 small form factor desktop - dell 755 desktop - lenovo thinkpad x201 I don't get the "try xubuntu / install xubuntu" screen, instead it eventually drops to ---- "BusyBox v1.27.2 (Ubuntu 1:1.27.2-2ubuntu4) built-in shell (ash) Enter 'help' for a list of built-in commands (initramfs) Unable to find a medium containing a live file system ---- Note: I typed the messages in so typos may exist I suspect it's the same issue as https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1794922 where Walter (wxl) gave a possible link to http://debian.2.n7.nabble.com/Bug-908924-dma-direct-map-sg-overflow- on-USB-access-after-upgrade-to-kernel-4-18-td4387757.html I've been testing xubuntu 18.10 daily images for awhile (but not logging on qa-tracker - my bad, sorry!!!) without issue on t43 & d610, and only rarely booting on other boxes (like 755/dc7700/..) It may have been ~15-20 days since last tested on dell 755; but it worked fine back then (& prior) but due to my QA-tracking omission, we can't be exact - sorry again!
