| |
Hi,
While trying to boot an EeePC 900 on the latest git mainline kernel a hang is encountered while systemd is starting services but this did not happen with 4.15. A bisection narrowed it down to the commit 358f70da49d77c43f2ca11b5da584213b2add29c ("blk-mq: make blk_abort_request() trigger timeout path"). Here's the bisection log:
