Hi, I copied everything of the disk, to a partition with some errors, but there were none on when I copied, remade the fs with mkfs.reiser4 -o create=ccreg40,compress=gzip1 and copied everything back, again, without problems or anything suspicious in dmesg. Before and after th exercise I get this whenever I open a directory in konqueror containing pictures; [ 84.131089] reiser4[kio_thumbnail(2347)]: do_readpage_ctail (fs/reiser4/plugin/item/ctail.c:677)[edward-1563]: [ 84.131090] WARNING: orphan unprepped cluster 0 (inode 11052573). Fsck? [ 84.131116] reiser4[kio_thumbnail(2347)]: do_readpage_ctail (fs/reiser4/plugin/item/ctail.c:677)[edward-1563]: [ 84.131117] WARNING: orphan unprepped cluster 0 (inode 11052573). Fsck? which completely floods dmesg, but seems to be harmless compared to the clusterfuck when I try to install icons or plasma themes via system-settings. As soon as I click the install button and the download starts, I get a kio_file crashed notification and find this gem in dmesg: [ 144.883228] BUG: unable to handle kernel NULL pointer dereference at 0000000000000050 [ 144.883234] IP: [<ffffffff8135628f>] _raw_spin_lock+0x9/0x1a [ 144.883241] PGD 1f80b1067 PUD 1f80f2067 PMD 0 [ 144.883244] Oops: 0002 [#1] SMP [ 144.883247] last sysfs file: /sys/devices/pci0000:00/0000:00:11.0/host3/target3:0:0/3:0:0:0/block/sdd/dev [ 144.883250] CPU 0 [ 144.883251] Modules linked in: snd_seq_midi snd_emu10k1_synth snd_emux_synth snd_seq_virmidi snd_seq_midi_emul snd_seq_dummy snd_seq_oss snd_seq_midi_event snd_seq snd_pcm_oss snd_mixer_oss snd_emu10k1 snd_rawmidi snd_ac97_codec ac97_bus snd_pcm snd_seq_device snd_timer snd_page_alloc snd_util_mem snd_hwdep snd asus_atk0110 usb_storage k10temp isl6421 b2c2_flexcop_pci b2c2_flexcop dvb_core cx24123 cx24113 s5h1420 ehci_hcd r8169 mii [ 144.883273] [ 144.883277] Pid: 2516, comm: kio_file Tainted: G W 2.6.34.7r4 #2 M4A79XTD EVO/System Product Name [ 144.883280] RIP: 0010:[<ffffffff8135628f>] [<ffffffff8135628f>] _raw_spin_lock+0x9/0x1a [ 144.883284] RSP: 0018:ffff8801f80f1a28 EFLAGS: 00010292 [ 144.883286] RAX: 0000000000000100 RBX: ffff8801f80f1af8 RCX: 0000000000000010 [ 144.883288] RDX: 0000000000000000 RSI: ffff880205872c08 RDI: 0000000000000050 [ 144.883290] RBP: ffff8801f80f1a28 R08: dead000000100100 R09: ffff8801f80f17e0 [ 144.883293] R10: ffff880212ab02c8 R11: ffff88020a388c40 R12: ffff880205872c08 [ 144.883295] R13: ffffea000716a080 R14: 0000000000000000 R15: 0000000000000000 [ 144.883298] FS: 00007fbea3634760(0000) GS:ffff880001800000(0000) knlGS:0000000000000000 [ 144.883300] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 144.883302] CR2: 0000000000000050 CR3: 00000001f80de000 CR4: 00000000000006f0 [ 144.883304] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 144.883306] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 [ 144.883309] Process kio_file (pid: 2516, threadinfo ffff8801f80f0000, task ffff88022ed011a0) [ 144.883311] Stack: [ 144.883312] ffff8801f80f1a78 ffffffff81122712 0000000000000000 00000000000080d0 [ 144.883315] <0> ffff8801f80f1a98 ffff8801f80f1af8 ffff880205872c08 ffffea000716a080 [ 144.883319] <0> 0000000000000000 0000000000000000 ffff8801f80f1ac8 ffffffff81124f7e [ 144.883324] Call Trace: [ 144.883329] [<ffffffff81122712>] checkin_logical_cluster+0x24/0x1c3 [ 144.883333] [<ffffffff81124f7e>] capture_page_cluster+0xab/0xe2 [ 144.883337] [<ffffffff8112508f>] write_end_cryptcompress+0xda/0x15f [ 144.883341] [<ffffffff811213bc>] reiser4_write_end_careful+0x10f/0x195 [ 144.883345] [<ffffffff810857bb>] pagecache_write_end+0x4e/0x57 [ 144.883349] [<ffffffff810cf9e8>] pipe_to_file+0x13e/0x14d [ 144.883352] [<ffffffff8103936d>] ? current_fs_time+0x22/0x29 [ 144.883356] [<ffffffff810cf8aa>] ? pipe_to_file+0x0/0x14d [ 144.883359] [<ffffffff810ced30>] splice_from_pipe_feed+0x53/0xe5 [ 144.883362] [<ffffffff810cf82f>] generic_file_splice_write+0xae/0x129 [ 144.883365] [<ffffffff810cf3d1>] do_splice_from+0x74/0x80 [ 144.883368] [<ffffffff810cf3f8>] direct_splice_actor+0x1b/0x1d [ 144.883371] [<ffffffff810cf668>] splice_direct_to_actor+0xd9/0x198 [ 144.883375] [<ffffffff810cf3dd>] ? direct_splice_actor+0x0/0x1d [ 144.883378] [<ffffffff810cf76e>] do_splice_direct+0x47/0x5a [ 144.883381] [<ffffffff810b34ba>] do_sendfile+0x131/0x182 [ 144.883385] [<ffffffff810b3558>] sys_sendfile64+0x4d/0x8d [ 144.883389] [<ffffffff81001feb>] system_call_fastpath+0x16/0x1b [ 144.883391] Code: 0f b7 07 38 e0 8d 90 00 01 00 00 75 05 f0 66 0f b1 17 0f 94 c2 0f b6 c2 85 c0 c9 0f 95 c0 0f b6 c0 c3 55 b8 00 01 00 00 48 89 e5 <f0> 66 0f c1 07 38 e0 74 06 f3 90 8a 07 eb f6 c9 c3 55 48 89 e5 [ 144.883413] RIP [<ffffffff8135628f>] _raw_spin_lock+0x9/0x1a [ 144.883416] RSP <ffff8801f80f1a28> [ 144.883418] CR2: 0000000000000050 [ 144.883431] ---[ end trace e5efc81aa3e933fe ]--- of course afterwards everything that tries to write to that partition is stuck in D, which reduces the usability of the box to zero, since it contains / and /home. There are no problems downloading to /tmp, which is on tempfs and moving the files to the partition, or when downloading stuff with chromium or firefox. Only kio_file and kio_thumbnail are hit. Hard. Questions: if I copy stuff to a known bad partition and copy those files back - are there chances to copy file system corruption? Is that stuff contagious? And the second question: has anybody else seen this problems?
