I mention this as Operating System selector does not include 12.1) I have been experiencing problems with iSCSI for a while. Until 11.3, everything was fine. 11.4 and 12.1 present problems. We start with a very simple 12.1 OpenSuSE installation: zypper install iscsiadm Afterward, we take a 100MB file /varios/01/iSCSI/archivaldo and add it to the ietd.conf /editar ietd.conf Target iqn.2011-10.yyyy.xxxx:fila Lun 0 Path=/varios/01/iSCSI/archivaldo,Type=fileio Afterward, we start iscsitarget, ~ # rciscsitarget start Starting iSCSI target service: FATAL: Error inserting crc32c_intel (/lib/modules/2.6.37.6-0.7-desktop/kernel/arch/x86/crypto/crc32c-intel.ko): No such device The error can be removed from the init script, but is irrelevant. The service works perfectly the first time it is accessed from a client machine. After we reboot 2 or 3 times the machine, we cannot access anymore to the lun and get the following error on the /var/log/messages Dec 5 10:14:18 linux-akxl iscsitarget[3704]: Starting iSCSI target service: FATAL: Error inserting crc32c_intel (/lib/modules/3.1.0-1.2-desktop/kernel/arch/x86/crypto/crc32c-intel.ko): No such device Dec 5 10:14:18 linux-akxl ietd: unable to lock pid file: Resource temporarily unavailable Dec 5 10:14:18 linux-akxl iscsitarget[3704]: ..done Dec 5 10:26:01 linux-akxl kernel: [ 2640.195710] iscsi_trgt: BUG at /home/abuild/rpmbuild/BUILD/iscsitarget-1.4.20-svn/obj/desktop/iscsi.c:392 assert(req->tio) Dec 5 10:26:01 linux-akxl kernel: [ 2640.208486] Pid: 2595, comm: istiod1 Not tainted 3.1.0-1.2-desktop #1 Dec 5 10:26:01 linux-akxl kernel: [ 2640.208492] Call Trace: Dec 5 10:26:01 linux-akxl kernel: [ 2640.208556] [<ffffffff810043fa>] dump_trace+0xaa/0x2b0 Dec 5 10:26:01 linux-akxl kernel: [ 2640.208567] [<ffffffff81582a4a>] dump_stack+0x69/0x6f Dec 5 10:26:01 linux-akxl kernel: [ 2640.208589] [<ffffffffa0258c32>] send_data_rsp+0xd2/0xe0 [iscsi_trgt] Dec 5 10:26:01 linux-akxl kernel: [ 2640.208623] [<ffffffffa0260f6f>] disk_execute_cmnd.part.0+0x18f/0x1d0 [iscsi_trgt] Dec 5 10:26:01 linux-akxl kernel: [ 2640.209372] [<ffffffffa0260fc9>] disk_execute_cmnd+0x19/0x20 [iscsi_trgt] Dec 5 10:26:01 linux-akxl kernel: [ 2640.209443] [<ffffffffa025be00>] worker_thread+0x160/0x2c0 [iscsi_trgt] Dec 5 10:26:01 linux-akxl kernel: [ 2640.209466] [<ffffffff81075c8e>] kthread+0x7e/0x90 Dec 5 10:26:01 linux-akxl kernel: [ 2640.209495] [<ffffffff815a5474>] kernel_thread_helper+0x4/0x10 Dec 5 10:26:01 linux-akxl kernel: [ 2640.210798] ------------[ cut here ]------------ Dec 5 10:26:01 linux-akxl kernel: [ 2640.211052] kernel BUG at /home/abuild/rpmbuild/BUILD/iscsitarget-1.4.20-svn/obj/desktop/iscsi.c:392!
