dmesg

Certain filesystem usage leads to one of the two errors visible in dmesg output (see attachment). The system needs a reboot after that.

I have also tested with olders kernel versions, including 2.6.38.8. Same there (at least for the first of the two errors).

Strangely, the only filesystem usage scheme that triggers those errors are two parallel processes of the bup backup system <https://github.com/apenwarr/bup>. They run fine for some time (several minutes, sometimes longer), then the bug message appears in the logs, and the system stops working correctly.

I am using an encrypted LVM.

Please test this bug against a newer kernel to see if it's fixed.
