So, one more time, I see the problem. This time I was just using Firefox and I cannot recover using `btrfs balance`. I think that, one more time, I will need to reboot this machine. This problem is really causing me a lot of troubles :( I have disabled the quotas and the first error message after the problem was: [ 2444.592255] ------------[ cut here ]------------ [ 2444.592314] WARNING: CPU: 4 PID: 289 at ../fs/btrfs/extent- tree.c:4303 btrfs_free_reserved_data_space_noquota+0xfe/0x110 [btrfs] [ 2444.592317] Modules linked in: fuse nf_log_ipv6 xt_pkttype nf_log_ipv4 nf_log_common xt_LOG xt_limit af_packet iscsi_ibft iscsi_boot_sysfs msr ip6t_REJECT nf_reject_ipv6 xt_tcpudp nf_conntrack_ipv6 nf_defrag_ipv6 ip6table_raw nvidia_drm(PO) ipt_REJECT nf_reject_ipv4 snd_hda_codec_hdmi nvidia_modeset(PO) intel_rapl sb_edac edac_core x86_pkg_temp_thermal intel_powerclamp nvidia(PO) coretemp snd_hda_codec_realtek iTCO_wdt snd_hda_codec_generic iptable_raw drm_kms_helper snd_hda_intel drm xt_CT snd_hda_codec snd_hda_core snd_hwdep kvm_intel snd_pcm snd_timer joydev mei_wdt fb_sys_fops iTCO_vendor_support i2c_i801 lpc_ich kvm syscopyarea snd sysfillrect irqbypass mei_me hp_wmi sysimgblt iptable_filter crct10dif_pclmul crc32_pclmul ghash_clmulni_intel aesni_intel aes_x86_64 lrw gf128mul glue_helper ablk_helper [ 2444.592386] cryptd soundcore mei sparse_keymap rfkill e1000e shpchp pcspkr ioatdma mfd_core tpm_infineon tpm_tis dca tpm fjes ptp pps_core ip6table_mangle nf_conntrack_netbios_ns nf_conntrack_broadcast nf_conntrack_ipv4 nf_defrag_ipv4 ip_tables xt_conntrack nf_conntrack ip6table_filter ip6_tables x_tables btrfs xor raid6_pq hid_generic usbhid crc32c_intel serio_raw xhci_pci ehci_pci xhci_hcd ehci_hcd firewire_ohci sr_mod firewire_core cdrom crc_itu_t usbcore isci usb_common libsas ata_generic mpt3sas raid_class scsi_transport_sas wmi button sg [ 2444.592447] CPU: 4 PID: 289 Comm: kworker/u65:7 Tainted: P W O 4.7.1-1-default #1 [ 2444.592450] Hardware name: Hewlett-Packard HP Z820 Workstation/158B, BIOS J63 v03.65 12/19/2013 [ 2444.592458] Workqueue: writeback wb_workfn (flush-btrfs-1) [ 2444.592462] 0000000000000000 ffffffff81393104 0000000000000000 0000000000000000 [ 2444.592468] ffffffff8107ca1e ffff88080de6d800 0000000000009000 ffff88080c437a00 [ 2444.592472] ffff880634b379ac 0000000000009000 ffff88080dcfb73c ffffffffa02af98e [ 2444.592477] Call Trace: [ 2444.592499] [<ffffffff8102ed5e>] dump_trace+0x5e/0x320 [ 2444.592507] [<ffffffff8102f12c>] show_stack_log_lvl+0x10c/0x180 [ 2444.592514] [<ffffffff8102fe41>] show_stack+0x21/0x40 [ 2444.592523] [<ffffffff81393104>] dump_stack+0x5c/0x78 [ 2444.592531] [<ffffffff8107ca1e>] __warn+0xbe/0xe0 [ 2444.592561] [<ffffffffa02af98e>] btrfs_free_reserved_data_space_noquota+0xfe/0x110 [btrfs] [ 2444.592602] [<ffffffffa02cc036>] btrfs_clear_bit_hook+0x296/0x380 [btrfs] [ 2444.592642] [<ffffffffa02e9755>] clear_state_bit+0x55/0x1d0 [btrfs] [ 2444.592676] [<ffffffffa02e9a0d>] __clear_extent_bit+0x13d/0x3f0 [btrfs] [ 2444.592707] [<ffffffffa02ea8d2>] extent_clear_unlock_delalloc+0x62/0x280 [btrfs] [ 2444.592739] [<ffffffffa02d1c19>] cow_file_range+0x299/0x440 [btrfs] [ 2444.592768] [<ffffffffa02d2cf2>] run_delalloc_range+0x392/0x3b0 [btrfs] [ 2444.592801] [<ffffffffa02eb090>] writepage_delalloc.isra.40+0x100/0x170 [btrfs] [ 2444.592834] [<ffffffffa02ed9d3>] __extent_writepage+0xc3/0x340 [btrfs] [ 2444.592864] [<ffffffffa02ede8b>] extent_write_cache_pages.isra.36.constprop.53+0x23b/0x350 [btrfs] [ 2444.592894] [<ffffffffa02ee4fe>] extent_writepages+0x4e/0x60 [btrfs] [ 2444.592900] [<ffffffff8123c64d>] __writeback_single_inode+0x3d/0x3b0 [ 2444.592907] [<ffffffff8123ce8a>] writeback_sb_inodes+0x20a/0x440 [ 2444.592914] [<ffffffff8123d147>] __writeback_inodes_wb+0x87/0xb0 [ 2444.592921] [<ffffffff8123d49d>] wb_writeback+0x28d/0x330 [ 2444.592927] [<ffffffff8123dbe2>] wb_workfn+0x222/0x3f0 [ 2444.592934] [<ffffffff810950ed>] process_one_work+0x1ed/0x4e0 [ 2444.592942] [<ffffffff81095427>] worker_thread+0x47/0x4c0 [ 2444.592947] [<ffffffff8109affd>] kthread+0xbd/0xe0 [ 2444.592954] [<ffffffff816bb71f>] ret_from_fork+0x1f/0x40 [ 2444.596679] DWARF2 unwinder stuck at ret_from_fork+0x1f/0x40 [ 2444.596683] Leftover inexact backtrace: [ 2444.596689] [<ffffffff8109af40>] ?
