Im really sorry that i cant provide logs, but i have no access to the logs as the system got broken by the udev-186 upgrade :P i will hand-type the logs and hope this will help (everyone _should_ be able to reproduce this easily) /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.1/../../../../lib64/liblvm2app.so: undefined reference to `udev_new` /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.1/../../../../lib64/liblvm2app.so: undefined reference to `udev_queue_get_udev_is_active` /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.1/../../../../lib64/liblvm2app.so: undefined reference to `udev_enumerate_scan_devices` /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.1/../../../../lib64/liblvm2app.so: undefined reference to `udev_unref` /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.1/../../../../lib64/liblvm2app.so: undefined reference to `udev_device_get_devlinks_list_entry` i bet it is related to bug 424810 Reproducible: Always Steps to Reproduce: 1. Uopgrade to udev 186 2. try to compile sys-fs/udisks-1.0.4-r2
unrelated to udisks, recompile your lvm2 against the new udev *** This bug has been marked as a duplicate of bug 424810 ***
