Re: [bugzilla-daemon@bugzilla.kernel.org: [Bug 205119] New: It takes long time to wake up from s2idle on Dell XPS 7390 2-in-1]

Hi,

Most likely not a regression as Ice Lake support was just added in
v5.4-rc1.

@AceLan, I've seen similar issue before and that was fixed by a BIOS/FW
upgrade. Can you check if there is newer BIOS/FW for that system and see
if it helps?

Let's continue debugging on bugzilla.
