Hello On my SPARC sunblade 100, I got this: [ 13.613727] rtc-m48t59 rtc-m48t59.0: IRQ index 0 not found [ 13.805777] rtc-m48t59 rtc-m48t59.0: registered as rtc0 [ 14.385092] rtc-m48t59 rtc-m48t59.0: setting system clock to 2021-03-01T05:34:33 UTC (1614576873) The IRQ index 0 message is found after 5.5 Testing rtc via hwclock give: hwclock: ioctl(3, RTC_UIE_ON, 0) to /dev/rtc0 failed: Input/output error But this hwclock behavior is present also on earlier kernel (tested 4.9.260, 4.19.179 and 4.14.224). Does this Input/output error is normal ? (I think no) Regards
