Filed as: https://bugzilla.opensuse.org/show_bug.cgi?id=1009339 After the Tumbleweed update yesterday I've run the btrfs balance script. Halfway thru it set the filesystem read-only. I've rebooted, it rebuild some free extent cache that it said was missing, created a new journal and I could then finish the rebalance. Today the filesystem has again hit some problem: [ 550.910590] ------------[ cut here ]------------ [ 550.910644] WARNING: CPU: 2 PID: 524 at ../fs/btrfs/extent-tree.c:6945 __btrfs_free_extent.isra.70+0x7f8/0xcc0 [btrfs] [ 550.910646] Modules linked in: fuse ip6t_REJECT nf_reject_ipv6 nf_log_ipv6 nf_conntrack_ipv6 nf_defrag_ipv6 ip6table_raw ipt_REJECT nf_reject_ipv4 xt_tcpudp xt_pkttype xt_ph ysdev br_netfilter nf_log_ipv4 nf_log_common xt_LOG xt_limit iptable_raw xt_CT iptable_filter ip6table_mangle nf_conntrack_netbios_ns nf_conntrack_broadcast nf_conntrack_ipv4 n f_defrag_ipv4 ip_tables xt_conntrack nf_conntrack ip6table_filter ip6_tables x_tables af_packet bridge stp llc iscsi_ibft iscsi_boot_sysfs msr nls_iso8859_1 nls_cp437 vfat xfs libcrc32c fat snd_hda_codec_realtek snd_hda_codec_generic intel_rapl x86_pkg_temp_thermal intel_powerclamp coretemp snd_emu10k1 snd_util_mem snd_rawmidi kvm_intel kvm snd_seq_d evice snd_ac97_codec irqbypass crct10dif_pclmul crc32_pclmul snd_hda_intel ghash_clmulni_intel snd_hda_codec [ 550.910718] aesni_intel snd_hda_core snd_hwdep pl2303 snd_pcm usbserial aes_x86_64 mei_wdt lrw iTCO_wdt i2c_i801 glue_helper iTCO_vendor_support dcdbas emu10k1_gp ablk_help er cryptd i2c_smbus pcspkr gameport ac97_bus snd_timer battery snd thermal ie31200_edac e1000e fjes tpm_tis soundcore mei_me lpc_ich tpm_tis_core ptp mei tpm pps_core edac_core shpchp mfd_core btrfs xor zlib_deflate raid6_pq crc32c_intel serio_raw sr_mod cdrom ehci_pci ehci_hcd i915 i2c_algo_bit drm_kms_helper syscopyarea xhci_pci sysfillrect sysimgb lt fb_sys_fops xhci_hcd usbcore drm usb_common button video dm_mirror dm_region_hash dm_log sg dm_multipath dm_mod scsi_dh_rdac scsi_dh_emc scsi_dh_alua efivarfs [ 550.910805] CPU: 2 PID: 524 Comm: btrfs-transacti Not tainted 4.8.6-2-default #1 [ 550.910807] Hardware name: Dell Inc.
