Beginning with kernel 3.15.1, I am getting hard lockups every time I connect a drive to my USB 3 HDD dock with ASMedia ASM1051E UASP compliant chipset. The only way I am able work around this is to set the quirk to ignore uas for the device. Here are the kernel messages during connection followed by a backtrace: [ 229.882190] usb 2-1: new SuperSpeed USB device number 3 using xhci_hcd [ 229.908001] usb-storage 2-1:1.0: USB Mass Storage device detected [ 229.908218] usb-storage 2-1:1.0: Quirks match for vid 174c pid 55aa: 400000 [ 229.908349] scsi7 : usb-storage 2-1:1.0 [ 230.912633] scsi 7:0:0:0: Direct-Access ASMT 2105 0 PQ: 0 ANSI: 6 [ 230.914818] sd 7:0:0:0: [sdc] Attached SCSI removable disk [ 289.680267] usb 2-1: USB disconnect, device number 3 [ 319.599862] usb 2-1: new SuperSpeed USB device number 4 using xhci_hcd [ 319.626881] scsi8 : uas [ 319.628221] xhci_hcd 0000:02:00.0: ERROR Transfer event TRB DMA ptr not part of current TD [ 320.029323] BUG: unable to handle kernel paging request at 0000000001000003 [ 320.029393] IP: [<ffffffff81198b0b>] kmem_cache_alloc+0x6b/0x170 [ 320.029445] PGD 40821a067 PUD 401bbf067 PMD 40411c067 PTE 0 [ 320.029505] Oops: 0000 [#1] PREEMPT SMP [ 320.029552] Modules linked in: uas usb_storage netconsole des_generic ecb md4 nls_utf8 cifs dns_resolver sch_fq_codel fuse nf_conntrack_ipv4 nf_defrag_ipv4 xt_tcpudp xt_conntrack nf_conntrack iptable_filter ip_tables x_tables vmnet(O) vsock vmci(O) vmmon(O) w83627ehf hwmon_vid adm1021 xfs libcrc32c nls_iso8859_1 nls_cp437 vfat fat coretemp hwmon iTCO_wdt intel_rapl iTCO_vendor_support x86_pkg_temp_thermal intel_powerclamp crct10dif_pclmul crc32_pclmul ppdev crc32c_intel snd_hda_codec_hdmi ghash_clmulni_intel aesni_intel snd_hda_codec_realtek snd_hda_codec_generic aes_x86_64 lrw gf128mul glue_helper ablk_helper cryptd e1000e hdpvr microcode evdev snd_hda_intel i915 joydev v4l2_dv_timings ptp mousedev psmouse r8168(O) mac_hid snd_hda_controller videodev serio_raw pcspkr media snd_hda_codec i2c_i801 lpc_ich pps_core snd_hwdep drm_kms_helper snd_pcm snd_timer drm snd battery tpm_tis parport_pc tpm intel_gtt parport i2c_algo_bit mei_me soundcore mei nuvoton_cir video shpchp button processor nfsd auth_rpcgss oid_registry nfs_acl nfs lockd fscache sunrpc lirc_zilog(C) i2c_core lirc_dev rc_core ext4 crc16 mbcache jbd2 hid_generic usbhid hid sd_mod crc_t10dif crct10dif_common atkbd libps2 ehci_pci xhci_hcd ehci_hcd firewire_ohci ahci libahci libata firewire_core crc_itu_t scsi_mod usbcore usb_common i8042 serio [ 320.030938] CPU: 0 PID: 782 Comm: mysqld Tainted: G C O 3.15.3-ARCH #1 [ 320.030988] Hardware name: To Be Filled By O.E.M.
