[RHEL5 Beta2] iscsi-initiator-utils: iscsid causes unaligned access on IA64.
Last modified: 2012-08-02 18:46:19 EDT
Description of problem: /etc/init.d/iscsi causes unaligned access on IA64. It's enabled by default. Version-Release number of selected component: iscsi-initiator-utils-6.2.0.695-0.5 How reproducible: Always Steps to Reproduce: 1. /etc/init.d/iscsi restart Actual results: iscsid causes unaligned access. --------------------------------------------------------------------- Oct 16 14:10:36 nec-tx7-2 kernel: iscsid(5530): unaligned access to 0x2000000000400101, ip=0x4000000000012e61 Oct 16 14:10:36 nec-tx7-2 kernel: iscsid(5530): unaligned access to 0x2000000000400101, ip=0x4000000000012e71 Oct 16 14:10:37 nec-tx7-2 iscsid: caught signal -15, ignoring... Oct 16 14:10:41 nec-tx7-2 kernel: Loading iSCSI transport class v2.0-685.<5>iscsi: registered transport (tcp) Oct 16 14:10:41 nec-tx7-2 iscsid: iSCSI logger with pid=5895 started!

Oct 16 14:10:42 nec-tx7-2 iscsid: an InitiatorAlias= is required, but was not found in /etc/iscsi/initiatorname.iscsi Oct 16 14:10:42 nec-tx7-2 iscsid: iSCSI sync pid=5901 started --------------------------------------------------------------------- Expected results: iscsid should not cause unaligned access. Additional info:
What kernel version are you running with? Do a uname -a? Does this also only occur on restart? Does it occur if you startup iscsi and setup sessions?
I tried kernel-2.6.18-1.2717.el5 and kernel-2.6.18-1.2727.el5. This occurs on start and stop. It seems to occur on "daemon iscsid" and "killproc iscsid". And I found that this occurs by: # modprobe iscsi_tcp # iscsid
Are you the same NEC people in westfird? Is this box in Red Hat somewhere by any chance?
*** Bug 248115 has been marked as a duplicate of this bug. ***
Not reproduced when testing with the latest nightly build including: kernel-2.6.18-85.el5 iscsi-initiator-utils-6.2.0.868-0.3.el5
There are still some in the logout or error handler paths though. I am going to fix them up in 5.3, so please keep this bug open.

I was not able to do a big update to iscsi-initiatior-utils and bring all the fixes I wanted. I am moving this to 5.4.
Sorry for delayed response..., but could you let me know about your tested version? I'll try it. As same as iscsi-initiator-utils-6.2.0.695-0.5 ? ---- #16 on Bug 211015 This is hard to reproduce, and may in fact have been fixed. Moving to 5.5, while we await confirmation. ---- (Copied from IT)
