http://bugzilla.opensuse.org/show_bug.cgi?id=944188 Bug ID: 944188 Summary: Kernel fills up /var/log/warn when accessing MMC Classification: openSUSE Product: openSUSE Distribution Version: 13.2 Hardware: x86-64 OS: Other Status: NEW Severity: Major Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: darren@freemaninstruments.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Using a kernel from OBS Kernel Stable, 4.1.6-2.gce0123d-desktop Running on a Dell Inspiron 1537, 64 bit. I just found my root filesystem basically full. The culprit is my /var/log/warn file which has grown to 1.8 GB. Inspecting the end of this file, the issue seems to be an almost endless repetition of the following. Yes, I have been accessing an SD-CARD over the last few days, reading and writing images for a Raspberry Pi. I can't even remember the last time that I'd used the MMC slot prior to that. I did notice my system running very sluggish during these operations. ------------[ cut here ]------------ 2015-09-01T14:19:47.224173+10:00 buffy kernel: [285775.355555] WARNING: CPU: 0 PID: 977 at ../drivers/mtd/nand/r852.c:749 r852_irq+0x1e1/0x260 [r852]() 2015-09-01T14:19:47.224175+10:00 buffy kernel: [285775.355556] Modules linked in: cdc_acm cytherm nls_iso8859_1 nls_cp437 vfat fat uas usb_storage mmc_block fuse rfcomm nf_log_ipv6 xt_pkttype xt_TCPMSS nf_log_ipv4 nf_log_common xt_LOG xt_limit scsi_transport_iscsi rpcsec_gss_krb5 auth_rpcgss nfsv4 dns_resolver nf s lockd grace sunrpc fscache vboxpci(O) vboxnetadp(O) vboxnetflt(O) vboxdrv(O) iscsi_ibft iscsi_boot_sysfs af_packet ip6t_REJECT xt_tcpudp nf_conntrack_ipv6 nf_defrag_ipv6 ip6table_raw ipt_REJECT iptable_raw xt_CT iptable_filter ip6table_mangle nf_conntrack_netbios_ns nf_conntrack_broadcast nf_conntrack_ipv4 nf_d efrag_ipv4 ip_tables xt_conntrack nf_conntrack ip6table_filter ip6_tables x_tables bnep btusb btbcm btintel bluetooth iTCO_wdt iTCO_vendor_support dell_wmi s parse_keymap uvcvideo snd_hda_codec_idt snd_hda_codec_generic videobuf2_vmalloc videobuf2_memops videobuf2_core snd_hda_codec_hdmi v4l2_common snd_hda_intel snd_hda_controller snd_hda_codec snd_hda_core snd_hwdep snd_pcm_oss videodev dell_laptop dcdbas coretemp kvm_intel i8k snd_pcm kvm pcspkr joydev serio_raw i2 c_i801 snd_seq snd_seq_device snd_timer lpc_ich mfd_core r852 sm_common nand nand_ecc nand_bch bch nand_ids mtd r592 memstick sdhci_pci sdhci mmc_core arc4 s nd_mixer_oss iwldvm mac80211 snd tg3 ptp pps_core libphy iwlwifi cfg80211 rfkill ir_xmp_decoder ir_lirc_codec lirc_dev ir_mce_kbd_decoder soundcore ir_sharp_ decoder ir_sanyo_decoder ir_sony_decoder shpchp ir_jvc_decoder ir_rc6_decoder thermal wmi ir_rc5_decoder ir_nec_decoder battery rc_rc6_mce acpi_cpufreq ite_c ir rc_core video ac button processor reiserfs dm_crypt twofish_generic twofish_x86_64_3way xts lrw gf128mul glue_helper twofish_x86_64 twofish_common algif_s kcipher af_alg firewire_ohci firewire_core crc_itu_t radeon i2c_algo_bit drm_kms_helper ttm drm dm_mirror dm_region_hash dm_log dm_mod sg 2015-09-01T14:19:47.224178+10:00 buffy kernel: [285775.355631] CPU: 0 PID: 977 Comm: systemd-journal Tainted: G W O 4.1.3-4.gf45c09a-desktop #1 2015-09-01T14:19:47.224181+10:00 buffy kernel: [285775.355632] Hardware name: Dell Inc.
