Hi, Thorsten here, the Linux kernel's regression tracker. Top-posting for once, to make this easily accessible to everyone. Gerd, it seems this regression[1] fell through the cracks. Could you please take a look? Or is there a good reason why this can't be addressed? Or was it dealt with and I just missed it? [1] apparently caused by 5a838e5d5825c8 ("drm/qxl: simplify qxl_fence_wait") [v5.13-rc1] from Gerd; for details see https://lore.kernel.org/regressions/ZTgydqRlK6WX_b29@xxxxxxxxxxx/ Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) -- Everything you wanna know about Linux kernel regression tracking: https://linux-regtracking.leemhuis.info/about/#tldr If I did something stupid, please tell me, as explained on that page. #regzbot poke On 24.10.23 23:39, Timo Lindfors wrote: > Hi, > > On Tue, 24 Oct 2023, Salvatore Bonaccorso wrote: >> Thanks for the excelent constructed report!
