14:56 <lucaceresoli> hello, I have a tegra20 board where rebooting does not work after upgrading from v5.17 to v5.18/v5.19/v6.0

14:56 <lucaceresoli> does this ring any bell? I tried reverting some reboot-related patches found in v5.17..v5.18 but to no avail

14:56 <lucaceresoli> I'm not bisecting v5.17..v5.18

15:31 <lucaceresoli> interesting, the first bad commit is 8bd4aaf438e3 ("media: staging: tegra-vde: De-stage driver") by digetx, clearly unrelated to rebooting

15:32 <lucaceresoli> however it does 2 things: renames TEGRA_VDE to VIDEO_TEGRA_VDE and moves it under an 'if V4L2_MEM2MEM_DEV'

15:33 <lucaceresoli> sp I enabled V4L2_MEM2MEM_DEV + VIDEO_TEGRA_VDE and now reboot is working

15:33 <lucaceresoli> I don't see how a video decode engine driver would affect rebooting :-?

15:46 <lucaceresoli> s/if V4L2_MEM2MEM_DEV/if V4L_MEM2MEM_DRIVERS/

16:24 <lucaceresoli> I investigated whether VIDEO_TEGRA_VDE indirectly selects the reset controller so that I foud it enabled by chance, but found no evidence of such a dependency

19:41 <digetx> kwizart: you'll either need to wait until somebody will fix it or bisect the bug and report it upstream, could be nouveau or iommu core regression

20:28 <lucaceresoli> digetx: thanks for the feedback, however I'm not sure I follow what's going on. I would expect the cpu to be able to reboot with or without a VDE driver, no?
