*Solved* BUG: scheduling while atomic: procd/1091/0x00000100

With Tenbay T-MB5EU-V01

This error occurs when i use the reboot command from LUCI but not all the time

With the power OFF / ON button I don't have this error and everything works fine

Please try latest master. I've pushed a Bugfix some days ago which should stop this warning from occurring.

Yes i have build last day OpenWrt SNAPSHOT, r18455-9ba6ee4e25
and warning no longer appears

Many thanks

This product is now working very well with 32M SPI flash.
It's a bit of a shame that the shape of the case is a bit weird.
I would have preferred a box a little identical to the Ancatus A6 which also has USB but no OpenWrt for the moment
