Hi All,

I'm sending this to the fedora-kernel and -devel lists
both to get the kernel team aware of this and because it
is not entirely clear to me how to best deal with this.

I guess we should get this added to the release-notes /
common-bugs page for F28, but I'm not sure what the
procedure is for that ?

Hi Hans,

I added it to the common bugs page:
https://fedoraproject.org/wiki/Common_F28_bugs#lpm-hang

Feel free to edit it in any way. If you want to add a new entry in the future, just read the guidelines linked on that page, it's very simple. Thanks :)

I've just become aware that at least for some users
the use of SATA LPM in F28 causes the Lenovo 50
series laptops (confirmed X250, T450s G50-80) freeze/
hang hard under certain conditions when using SATA
LPM, independent of the disk used (*).

I have T450s and haven't seen any hang yet, but I've been using F28 on it just for 2 days now. I'll let you know if it happens.
