No luck with the Xenial kernel (4.4.0-22), I could repro the crash 2 times (after a couple of hours each). Testing the Wily kernel next.
Here is the relevant part of the logs (both crashes produced near identical logs): Jun 07 20:19:44 muchcrash02 kernel: sd 2:0:0:0: Device offlined - not ready after error recovery Jun 07 20:19:44 muchcrash02 kernel: sd 2:0:0:0: [sda] tag#73 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_OK Jun 07 20:19:44 muchcrash02 kernel: sd 2:0:0:0: [sda] tag#73 CDB: Write(10) 2a 00 01 16 6c 00 00 04 00 00 Jun 07 20:19:44 muchcrash02 kernel: blk_update_request: I/O error, dev sda, sector 18246656 Jun 07 20:19:44 muchcrash02 kernel: sd 2:0:0:0: rejecting I/O to offline device Jun 07 20:19:44 muchcrash02 kernel: sd 2:0:0:0: [sda] killing request Jun 07 20:19:44 muchcrash02 kernel: sd 2:0:0:0: rejecting I/O to offline device Jun 07 20:19:44 muchcrash02 kernel: sd 2:0:0:0: [sda] FAILED Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK Jun 07 20:19:44 muchcrash02 kernel: sd 2:0:0:0: [sda] CDB: Write(10) 2a 00 01 17 60 00 00 04 00 00 Jun 07 20:19:44 muchcrash02 kernel: blk_update_request: I/O error, dev sda, sector 18309120 Jun 07 20:19:44 muchcrash02 kernel: EXT4-fs warning (device sda1): ext4_end_bio:329: I/O error -5 writing to inode 921923 (offset 234881024 size 8388608 starting block 2288896) Jun 07 20:19:44 muchcrash02 kernel: Buffer I/O error on device sda1, logical block 2288384 ..
