After testing if 5.9.0 worked on my rp2470, I comiled yesterdays git (v5.9-12462-gf804b3159482) and it boots up partially - no network but there is console login on serial. Noticed in dmesg: [ 14.403317] process '/sbin/init' started with executable stack [ 54.239069] systemd-udevd[460]: Failed to create SIGINT event source: Invalid argument [ 57.338167] systemd-udevd[673]: Failed to create SIGINT event source: Invalid argument [ 59.641694] ext2 filesystem being mounted at /boot supports timestamps until 2038 (0x7fffffff) [ 161.131316] systemd-udevd[1494]: Failed to create SIGINT event source: Invalid argument As to why there is no network: * There is dhcp client process /sbin/dhcpcd -q * tail -n 50 /var/log/messages gives lines for syslogd startup each second: Oct 22 09:51:54 rp2470 syslog-ng[6109]: syslog-ng starting up; version='3.26.1' So it seems syslogd dies and is restarted in a loop. And there does not appear anything else in the messages for this boot, only shutdown of previous boot. Is it something that might be known already? If not, I will try to bisect it if I get some time. -- Meelis Roos <mroos@xxxxxxxx>
