OK, I'll update and let the reporter testing it.Sorry, platform_device_alloc() and platform_device_add() were missing in the earlier patch. New patch atached. Dmitry, does this look correct?Please consider this one instead.
The patch was confirmed to work. https://bugzilla.suse.com/show_bug.cgi?id=1190256#c19 | That one worked despite the CTR error: | | [ 0.000000] Linux version 5.14.2-3.g9458b22-default (geeko@buildhost) (gcc (SUSE Linux) 11.2.1 20210816 [revision 056e324ce46a7924b5cf10f61010cf9dd2ca10e9], GNU ld (GNU Binutils; openSUSE Tumbleweed) 2.36.1.20210326-4) #1 SMP Sun Sep 12 20:15:58 UTC 2021 (9458b22) | [ 0.484315] i8042: PNP: PS/2 Controller [PNP0303:PS2K] at 0x60,0x64 irq 1 | [ 0.484318] i8042: PNP: PS/2 appears to have AUX port disabled, if this is incorrect please boot with i8042.nopnp | [ 1.005361] i8042: Can't read CTR while initializing i8042 | [ 1.477053] serio: i8042 KBD port at 0x60,0x64 irq 1 | [ 1.503700] input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input2 | | Seems it takes more than a secod to initialize, ugh I'm not sure what's done during this 0.5 second period after CTR read failure. At least only shuffling the driver init order for built-in drivers didn't suffice. A full log was requested, but I don't think it'll give much more information. Takashi
