Last good Kernel was 2.6.37 I'm doing a "mount" then "unmount". I think root is the only created inode. rmmod is called immediately after "unmount" within a script if I only do unmount and manually call "modprobe --remove exofs" after a small while all is fine. I get: slab error in kmem_cache_destroy(): cache `exofs_inode_cache': Can't free all objects Call Trace: 77dfde08: [<6007e9a6>] kmem_cache_destroy+0x82/0xca 77dfde38: [<7c1fa3da>] exit_exofs+0x1a/0x1c [exofs] 77dfde48: [<60054c10>] sys_delete_module+0x1b9/0x217 77dfdee8: [<60014d60>] handle_syscall+0x58/0x70 77dfdf08: [<60024163>] userspace+0x2dd/0x38a 77dfdfc8: [<600126af>] fork_handler+0x62/0x69 The UML Kernel also crashes after this message, with: Modules linked in: nfsd exportfs nfs lockd nfs_acl auth_rpcgss sunrpc cryptomgr aead crc32c crypto_hash crypto_algapi iscsi_tcp libiscsi_tcp libiscsi scsi_transport_iscsi scsi_mod binfmt_misc [last unloaded: libosd] Pid: 6, comm: rcu_kthread Not tainted 2.6.38-rc3+ RIP: 0033:[<000000007c1fa0e7>] RSP: 000000007943be18 EFLAGS: 00010246 RAX: 000000007943a000 RBX: 000000007937bb80 RCX: 0000000000000095 RDX: 000000007937c8b8 RSI: 0000000077fb6c80 RDI: 000000007937bb80 RBP: 000000007943be40 R08: 000000007943be10 R09: 000000007943a000 R10: 0000000000000000 R11: 0000000000000000 R12: 00000000795123e0 R13: 0000000000000001 R14: 0000000000000000 R15: 000000000000000a Call Trace: 602678f8: [<600144ed>] segv+0x70/0x212 60267928: [<6001cd9e>] ubd_intr+0x72/0xdf 60267988: [<601b778e>] _raw_spin_unlock_irqrestore+0x18/0x1c 602679d8: [<600146ee>] segv_handler+0x5f/0x65 60267a08: [<60021488>] sig_handler_common+0x84/0x98 60267ab0: [<60130926>] strncpy+0xf/0x27 60267b38: [<600215ce>] sig_handler+0x30/0x3b 60267b58: [<60021800>] handle_signal+0x6d/0xa3 60267ba8: [<60023180>] hard_handler+0x10/0x14 Kernel panic - not syncing: Segfault with no mm Call Trace: 602677f8: [<601b52b1>] panic+0xea/0x1e6 60267818: [<6007e299>] kmem_cache_free+0x54/0x5f 60267850: [<6005342e>] __module_text_address+0xd/0x53 60267868: [<6005347d>] is_module_text_address+0x9/0x11 60267878: [<6004290c>] __kernel_text_address+0x65/0x6b 60267880: [<60023180>] hard_handler+0x10/0x14 60267898: [<6001345e>] show_trace+0x8e/0x95 602678c8: [<60026c40>] show_regs+0x2b/0x2f 602678f8: [<60014577>] segv+0xfa/0x212 60267928: [<6001cd9e>] ubd_intr+0x72/0xdf 60267988: [<601b778e>] _raw_spin_unlock_irqrestore+0x18/0x1c 602679d8: [<600146ee>] segv_handler+0x5f/0x65 60267a08: [<60021488>] sig_handler_common+0x84/0x98 60267ab0: [<60130926>] strncpy+0xf/0x27 60267b38: [<600215ce>] sig_handler+0x30/0x3b 60267b58: [<60021800>] handle_signal+0x6d/0xa3 60267ba8: [<60023180>] hard_handler+0x10/0x14 Modules linked in: nfsd exportfs nfs lockd nfs_acl auth_rpcgss sunrpc cryptomgr aead crc32c crypto_hash crypto_algapi iscsi_tcp libiscsi_tcp libiscsi scsi_transport_iscsi scsi_mod binfmt_misc [last unloaded: libosd] Pid: 6, comm: rcu_kthread Not tainted 2.6.38-rc3+ RIP: 0033:[<0000003ea3832ad7>] RSP: 00007fff63338e38 EFLAGS: 00000202 RAX: 0000000000000000 RBX: 0000000000000219 RCX: ffffffffffffffff RDX: 0000000000000000 RSI: 0000000000000013 RDI: 0000000000000219 RBP: 00007fff63338e70 R08: 0000000000000000 R09: 00007fff63338e70 R10: 00007fff63338be0 R11: 0000000000000202 R12: 0000000000000215 R13: 00007fe54ee756a8 R14: 00007fff63339090 R15: 00007fff63339928 Call Trace: 60267788: [<6001485b>] panic_exit+0x2f/0x45 602677a8: [<60048ad6>] notifier_call_chain+0x32/0x5e 602677e8: [<60048b24>] atomic_notifier_call_chain+0x13/0x15 602677f8: [<601b52cc>] panic+0x105/0x1e6 60267818: [<6007e299>] kmem_cache_free+0x54/0x5f 60267850: [<6005342e>] __module_text_address+0xd/0x53 60267868: [<6005347d>] is_module_text_address+0x9/0x11 60267878: [<6004290c>] __kernel_text_address+0x65/0x6b 60267880: [<60023180>] hard_handler+0x10/0x14 60267898: [<6001345e>] show_trace+0x8e/0x95 602678c8: [<60026c40>] show_regs+0x2b/0x2f 602678f8: [<60014577>] segv+0xfa/0x212 60267928: [<6001cd9e>] ubd_intr+0x72/0xdf 60267988: [<601b778e>] _raw_spin_unlock_irqrestore+0x18/0x1c 602679d8: [<600146ee>] segv_handler+0x5f/0x65 60267a08: [<60021488>] sig_handler_common+0x84/0x98 60267ab0: [<60130926>] strncpy+0xf/0x27 60267b38: [<600215ce>] sig_handler+0x30/0x3b 60267b58: [<60021800>] handle_signal+0x6d/0xa3 60267ba8: [<60023180>] hard_handler+0x10/0x14 Thanks Boaz -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
