Title:
Hanging I/O causes multipath not to work properly
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
After switching a few times between paths I noticed that device-mapper
started logging the following messages:

[ 2478.346588] device-mapper: ioctl: error adding target to table
And in the output of echo w /proc/sysrq-trigger I noticed that
several I/O threads were hanging:

[Kernel-packages] [Bug 1094838] Re: 1002:68e0 [Acer Aspire 7551] BUG: unable to handle kernel NULL pointer dereference at 00000000000001d0; RIP: 0010:[ffffffffa02a054f] [ffffffffa02a054f] _ZN17Seg
Since I reported this bug I have switched from the fglrx driver to the in-tree Radeon driver because the fglrx driver was causing too much trouble. I have also switched from GNOME 3 to xfce to get rid of Compiz. After these two changes Ubuntu is running reliably on my laptop. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1094838 Title: 1002:68e0 [Acer Aspire 7551] BUG: unable to handle kernel NULL pointer dereference at 01d0; RIP: 0010:[a02a054f] [a02a054f] _ZN17SegmentMapManager13deleteMappingEP9CMMClient+0x3f/0x170 [fglrx] Status in “linux” package in Ubuntu: Incomplete Bug description: From /var/log/syslog: [ 1099.597490] [fglrx] IRQ 46 Disabled [ 1100.610392] BUG: unable to handle kernel NULL pointer dereference at 01d0 [ 1100.610545] IP: [a02a054f] _ZN17SegmentMapManager13deleteMappingEP9CMMClient+0x3f/0x170 [fglrx] [ 1100.610850] PGD 0 [ 1100.610894] Oops: [#1] SMP [ 1100.610961] CPU 0 [ 1100.610996] Modules linked in: ip6table_filter ip6_tables ebtable_nat ebtables ipt_MASQUERADE iptable_nat nf_nat nf_conntrack_ipv4 nf_defrag_ipv4 xt_state nf_conntrack ipt_REJECT xt_CHECKSUM iptable_mangle xt_tcpudp iptable_filter ip_tables x_tables bridge stp joydev kvm_amd kvm rfcomm parport_pc bnep ppdev bluetooth dm_crypt binfmt_misc snd_hda_codec_hdmi snd_hda_codec_realtek snd_hda_intel snd_seq_midi snd_hda_codec snd_hwdep snd_pcm snd_rawmidi snd_seq_midi_event fglrx(P) snd_seq arc4 sp5100_tco snd_timer snd_seq_device uvcvideo videodev snd psmouse v4l2_compat_ioctl32 soundcore edac_core serio_raw snd_page_alloc i2c_piix4 edac_mce_amd k10temp ath9k mac80211 ath9k_common ath9k_hw ath mac_hid cfg80211 lp parport vesafb usbhid hid pata_atiixp tg3 video wmi [ 1100.612011] [ 1100.612011] Pid: 4740, comm: Xorg Tainted: P O 3.2.0-35-generic #55-Ubuntu AcerAspire 7551/Aspire 7551 [ 1100.612011] RIP: 0010:[a02a054f] [a02a054f] _ZN17SegmentMapManager13deleteMappingEP9CMMClient+0x3f/0x170 [fglrx] [ 1100.612011] RSP: 0018:8800a270fb78 EFLAGS: 00010296 [ 1100.612011] RAX: RBX: c90002116e20 RCX: [ 1100.612011] RDX: c90002116e20 RSI: c9000219a6c0 RDI: 0150 [ 1100.612011] RBP: c9000219a6c0 R08: 0a6d R09: c9000210e860 [ 1100.612011] R10: a0344030 R11: R12: 8800a270fb98 [ 1100.612011] R13: 01d0 R14: c9000219a6c0 R15: 0150 [ 1100.612011] FS: 7f287368a880() GS:88013fc0() knlGS: [ 1100.612011] CS: 0010 DS: ES: CR0: 80050033 [ 1100.612011] CR2: 01d0 CR3: 01c05000 CR4: 06f0 [ 1100.612011] DR0: DR1: DR2: [ 1100.612011] DR3: DR6: 0ff0 DR7: 0400 [ 1100.612011] Process Xorg (pid: 4740, threadinfo 8800a270e000, task 8800a26e5c00) [ 1100.612011] Stack: [ 1100.612011] c9000210e9f0 [ 1100.612011] c9000210e820 c90001930fa0 [ 1100.612011] 01d0 c900019adea0 88011e278068 c90002116e20 [ 1100.612011] Call Trace: [ 1100.612011] [a02a2db0] ? _ZN3MSF9free_surfEP9CMMDriverP10CMMSurface+0x50/0xe0 [fglrx] [ 1100.612011] [a02c9fa8] ? _ZN9CMMClient17freeOwnedSurfacesEP9CMMDriver+0x88/0xe0 [fglrx] [ 1100.612011] [a02a4cca] ? _ZN10QS_PRIVATE16unRegisterClientEj+0xea/0x120 [fglrx] [ 1100.612011] [a02b5a2f] ? _ZN21CMMClientManager_CORE13destroyClientEP9CMMDriverP9CMMClient+0x2f/0x60 [fglrx] [ 1100.612011] [a02a1bdc] ? _ZN3CMM15releaseChildrenEv+0x14c/0x320 [fglrx] [ 1100.612011] [a029cdc9] ?
