Hi Guys, I have a server with the Marvell SAS HBA and in the newer versions of the kernel I have been seeing a whole bunch of this "sysfs group not found for kobject" warnings when a drive is removed; I am specifically trying to get the 3.16 kernel up and running. Looking around I found there were a few reports and patches on this issue which have been included in and around 3.14. The last one (I believe) was by Joe Lawrence (scsi_transport_sas: move bsg destructor into sas_rphy_remove). I checked the sources and looks like all patches are included but I still see this issue. Could this be an issue with the order in which mvsas driver does the tear down during drive removal? Following is a snippet of the trace. I have attached the full logs to the mail which contains rest of the trace with all the warnings related to a drive removal. Any ideas? Thanks, Praveen [ 2338.512534] ------------[ cut here ]------------ [ 2338.512551] WARNING: CPU: 2 PID: 6 at fs/sysfs/group.c:219 device_del+0x40/0x1c0() [ 2338.512557] sysfs group ffffffff818b97e0 not found for kobject '2:0:4:0' [ 2338.512561] Modules linked in: g_mass_storage usb_f_mass_storage libcomposite firewire_sbp2 iptable_filter ip_tables x_tables joydev sg hid_multitouch usbhid hid firewire_ohci firewire_core crc_itu_t uhci_hcd scsi_transport_iscsi evdev via_rng rng_core kvm_intel dm_dmirror dm_zcache dm_mod kvm padlock_aes snd_hda_codec_hdmi psmouse snd_hda_codec_via padlock_sha pcspkr snd_hda_codec_generic serio_raw tpm_tis tpm xhci_hcd ehci_pci ehci_hcd shpchp usb3380 ac udc_core snd_hda_intel snd_hda_controller snd_hda_codec snd_hwdep snd_pcm video r8169 mii snd_timer snd soundcore mvsas iscsi_target_mod processor target_core_mod button configfs sswipe libsas scsi_transport_sas picdev usbcore usb_common via_cputemp hwmon_vid fuse parport_pc ppdev lp parport autofs4 ext4 crc16 mbcache jbd2 s3g(PO) sd_mod crc_t10dif crct10dif_common ahci libahci libata scsi_mod fan thermal_sys s3g_drm(O) drm i2c_core [last unloaded: libcomposite] [ 2338.512724] CPU: 2 PID: 6 Comm: kworker/u8:0 Tainted: P W O 3.16.7-ckt9-logicube-ng.3 #1 [ 2338.512729] Hardware name: To be filled by O.E.M.
