#18092: jffs2_lzma segfault when installing package
-------------------------------------------+-------------------------------
Reporter: mk-openwrt@… | Owner: developers
Type: defect | Status: new
Priority: high | Milestone:
Component: base system | Version: Barrier Breaker
Keywords: lantiq, jffs2, lzma, segfault | 14.07
-------------------------------------------+-------------------------------
I tried to setup extroot on a vanilla barrier breaker flashed device
(ARV752DPW22).
Installing kmod-fs-ext4 reproducibly segfaults:
{{{
root@OpenWrt:/tmp# opkg install kmod-fs-ext4_3.10.49-1_lantiq.ipk
Installing kmod-fs-ext4 (3.10.49-1) to root...
Segmentation fault
