Package: iscsitarget-dkms Version: 1.4.20.2-10 Severity: important Dear Maintainer,
ata smart commands generates kernel call trace and kernel process istd1 hangs running at 100% cpu. iscsi target becomes unuseable unless reboot for example, I ran smartctl -i sdl on my windows xp initiator. this is how kernel has responded: [21974.560657] iscsi_trgt: BUG at /var/lib/dkms/iscsitarget/1.4.20.2/build/kernel/iscsi.c:392 assert(req->tio) [21974.560667] Pid: 3288, comm: istiod1 Tainted: G O 3.2.0-3-amd64 #1 [21974.560671] Call Trace: [21974.560683] [<ffffffffa04c53f1>] ? send_data_rsp+0x45/0x1f4 [iscsi_trgt] [21974.560691] [<ffffffffa04ce093>] ? ua_pending+0x19/0xa5 [iscsi_trgt] [21974.560698] [<ffffffffa04ccda8>] ? disk_execute_cmnd+0x1cf/0x22d [iscsi_trgt] [21974.560705] [<ffffffffa04c8a3d>] ? worker_thread+0xfd/0x255 [iscsi_trgt] [21974.560711] [<ffffffff8103f48f>] ? try_to_wake_up+0x197/0x197 [21974.560717] [<ffffffffa04c8940>] ? nthread_stop+0x35/0x35 [iscsi_trgt] [21974.560724] [<ffffffff8105efad>] ? kthread+0x76/0x7e [21974.560730] [<ffffffff81351df4>] ? kernel_thread_helper+0x4/0x10 [21974.560735] [<ffffffff8105ef37>] ? kthread_worker_fn+0x139/0x139 [21974.560740] [<ffffffff81351df0>] ? gs_change+0x13/0x13 [21974.560767] ------------[ cut here ]------------ [21974.560770] kernel BUG at /var/lib/dkms/iscsitarget/1.4.20.2/build/kernel/iscsi.c:392!
