SDHCI Regression with 6ce3dd6eec11 ("blk-mq: issue directly if hw queue isn't busy in case of 'none'")

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi

I bisected some kind of SDHCI regression to commit 6ce3dd6eec11 ("blk-mq: issue directly if hw queue isn't busy in case of 'none'") causing dumps below and one or more systemd-udevd processes being in uninterruptible sleep state preventing safe reboot/shutdown.

This is from an Intel Baytrail based tablet with integrated eMMC but my up-to-date Debian/testing rootfs (with systemd) is on USB stick.

It doesn't revert cleanly on today's head 778a33959a8a but issue is gone if I go to a commit before 6ce3dd6eec11 and occurs at 6ce3dd6eec11.
