Dear AngeloGioacchino, Dear Maintainers,
on MT8192 Asurada Spherion (Acer 514), I observe the following sleep
hang, causing a failure to suspend the system. The hang looks related to
the deadlock you fixed for MT8195 Tomato Chromebook in the past, thus
I'm including you in the To: line. The sleep hang happens with both
v6.5.4 as well as v6.5.4 with tags/mediatek-drm-next-6.6 merged in. (I'm
unable to validate v6.6-rc2 currently, as there's a regression breaking
boot.) Please let me know if I can provide any additional information to
help debug this issue or if you have any ideas how to address this bug.
