the configuration worked from core update138 flawlessly but with 142 the ppp modem cannot connect anymore.

[ 11.597907] FAT-fs (sda2): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.
The FAT-fs error may result from the problem, that ipfire cannot be shutdown with power-off (so i have to unplug the cable - when discs are synced, Prepare for halt… has passed and light on APU is off of course …)
Even with “shutdown -h now” the system restarts with “reboot: Power down” … maybe the runlevel has a wrong acpi flag or the coreboot of the apu4 has some WOL function, but i could not even figure out how to enter the coreboot (if that is possible)
