Runs very well on boot up. Then after some interval ranging from minutes to days, the following typical error occurs, repeated numerous times with differing blocks:
Mon Jul 24 07:09:39 2017 kern.err kernel: [43650.730023] SQUASHFS error: xz decompression failed, data probably corrupt
Mon Jul 24 07:09:39 2017 kern.err kernel: [43650.735459] SQUASHFS error: squashfs_read_data failed to read block 0x1e5d9a
Following this the unit becomes unresponsive, very slow or reboots its self.
Tried on two different devices and get the same result.
Images produced with Imagebuilder with ipv6, usb, ppp, luci removed to give space on flash.
The exact same config on OpenWrt CC (but with php5) gives no problems.
