--- Comment #9 from Graham Perrin <[email protected]> ---
(In reply to Vladimir Kondratyev from comment #6)
Testing. Thanks, everyone.
Up for four hours, panic-free, with:
* patched n252450-5efa7281a79
* drm-devel-kmod-5.5.19.g20211230
Prior to patching:
* the shortest bugged uptime was probably less than ten minutes
(maybe panictastic when setting a particular combination of
compositor preferences in KDE Plasma)
* the longest bugged uptime was around ten-and-a-half hours
(a panic not long after 19:22:25 GMT completion of buildkernel).
