Yijing Wang <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #4 from Yijing Wang <[email protected]> --- I also found the same issue when remove my disk in my platform, I think the code logic is incorrect, this call trace would appear every disk remove. I found Dan Williams posted a fix patch, but it was not merged to kernel. https://www.mail-archive.com/[email protected]/msg39187.html Following is my call trace: WARNING: CPU: 2 PID: 6 at fs/sysfs/group.c:224 sysfs_remove_group+0x9c/0xa0() sysfs group (power)ffff800000a2dbe8 not found for kobject '0:0:1:0' Modules linked in: CPU: 2 PID: 6 Comm: kworker/u64:0 Not tainted 4.1.6+ #157 Hardware name: Hisilicon PhosphorV660 Development Board (DT) Workqueue: scsi_wq_0 sas_destruct_devices Call trace: [<ffff800000089918>] dump_backtrace+0x0/0x124 [<ffff800000089a4c>] show_stack+0x10/0x1c [<ffff8000006ecd10>] dump_stack+0x78/0x98 [<ffff80000009fc38>] warn_slowpath_common+0x98/0xd0 [<ffff80000009fcbc>] warn_slowpath_fmt+0x4c/0x58 [<ffff8000001fc190>] sysfs_remove_group+0x98/0xa0 [<ffff8000003d7afc>] dpm_sysfs_remove+0x54/0x68 [<ffff8000003cca20>] device_del+0x3c/0x208 [<ffff8000003ccbfc>] device_unregister+0x10/0x2c [<ffff800000307810>] bsg_unregister_queue+0xbc/0xf8 [<ffff8000003fa3b0>] __scsi_remove_device+0x9c/0xbc [<ffff8000003fa414>] scsi_remove_device+0x44/0x64 [<ffff8000003fa604>] scsi_remove_target+0x198/0x258 [<ffff80000040c090>] sas_rphy_remove+0x8c/0xb4 [<ffff80000040c0ec>] sas_rphy_delete+0x34/0x54 [<ffff8000004102d0>] sas_destruct_devices+0x60/0x98 [<ffff8000000b5490>] process_one_work+0x13c/0x344 [<ffff8000000b57d4>] worker_thread+0x13c/0x494 [<ffff8000000bafb8>] kthread+0xd8/0xf0 -- You are receiving this mail because: You are the assignee for the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
