May 08 06:32:39 <suniel17> Hi all, I have a board based on Rockchip RK3399 64-bit SOC ARMv8A.I have installed Ubuntu focal fossa with LXDE Display manager. I am bootingvia NVMe SSD, the board loses power(powered off) automatically duringthe boot process. found out that this is happenning when systemd-udevd is setting up ubuntu user space (loading rules from udev/rules.d).Can
May 08 06:32:39 <suniel17> any one please comment on this issue and suggest how to fix the problem. Thanks
May 08 10:55:30 <tomreyn> suniel17: is the SoC's firmware actually capable of booting this way?
May 08 10:56:20 <tomreyn> hmm, actually, if you get until systemd-udevd i guess it did
May 08 10:58:08 <tomreyn> i'd still check whether that's ever been done successfully, the board powering off doesn't sound like ubuntu would have caused that
May 08 11:08:46 <suniel17> actually the board can boot from SD, emmc and USB apart from SSD.
May 08 11:09:07 <suniel17> SD, emmc and USB are booting fine, the problem is with SSD
May 08 11:53:24 <tomreyn> if you can find out what's being mishandled about the ssd by udev then you could create a udev rule for the pci device, having udev handle it properly, or just ignore it.
May 08 11:53:33 <tomreyn> suniel17: ^
May 08 11:58:31 <suniel17> yes, i am trying to figure out the problem, but couldnt narrow it down further, still trying
May 08 12:01:03 <ogra> most likely something is missing in your kernel that whatever the userspace does after the rules are processes is not available
May 08 12:01:07 <ogra> some config option
May 08 12:01:25 <ogra> (a i said yesterday already ...)
May 08 12:02:22 <suniel17> ok will look in that direction as well
