rtc-efi is unreachable #12

Open ggardet opened 3 years ago

ggardet commented 3 years ago

From openSUSE Tumbleweed (kernel 5.11.6) with latest firmware, I cannot read rtc-efi.

Kernel log:

[    2.717445] rtc-efi rtc-efi.0: registered as rtc0
[    2.719612] rtc-efi rtc-efi.0: hctosys: unable to read the hardware clock

And if I try to read it from user-space:

hwclock: ioctl(RTC_RD_TIME) to /dev/rtc0 to read the time failed: Input/output error

Is it something known?

I am running multiple distros as well as ESXi without issues, this is including 5.11.9 on Fedora 34 without issues.

Not sure if it could be related, but I noticed the following error message: ERROR: No descriptor returned from SEC between:

EFI stub: Booting Linux Kernel...
EFI stub: Using DTB from configuration table

and:

EFI stub: Exiting boot services and installing virtual address map...

Nope that is fine. That just means your are running edk2 without secure storage and no signed certificates are available.

You should probably drop into the uefi shell and verify your date and time are working there.

ggardet commented 3 years ago

From the UEFI shell, date returns 08/28/2028 and time returns 28:28:28 (LOCAL) which looks wrong!

jnettlet commented 3 years ago

please set them manually to something close to normal and see if that fixes the issue.

Unfortunately, Shell> date 03/26/2021 returns date: Invalid argument - '03/26/2021' And time 13:53 returns no error, but has no effect.

Were you previously running u-boot on this system? Are you running one of our prebuilt uefi images?

I tried u-boot when I got the system long time ago, but switched to edk2 based uefi long time ago. I built locally the firmware from latest sources. I can try a pre-built image if you point me to it.

Same behavior with pre-built image lx2160acex7_2000_700_2600_8_5_2_sd_4a89463.img.xz
