Subject: kernel problems with smart on LSI-92xx
Date: Wed, 10 Nov 2010 01:27:25 +0600 [thread overview]
Message-ID: <4CD9A09D.7000508@ngs.ru> (raw)

Hello.
I have kernel problems when trying to run smart commands on LSI-92xx
controller.
Running self-test on SAS disk (smartctl /dev/sda -dmegaraid,24 -t long)
with smartmontools causes kernel oops (?) (and segfault). Look in
attachment for dmesg.
strace of smartctl:
mknod("/dev/megaraid_sas_ioctl_node", S_IFCHR, makedev(251, 0)) = -1 EEXIST
(File exists)
close(4) = 0
munmap(0x7f4be3a9f000, 4096) = 0
open("/dev/megaraid_sas_ioctl_node", O_RDWR) = 4
ioctl(4, MTRRIOC_SET_ENTRY, 0x7fffa574ed30) = 0
ioctl(4, MTRRIOC_SET_ENTRY, 0x7fffa574eb30) = 0
ioctl(4, MTRRIOC_SET_ENTRY <unfinished ...>
+++ killed by SIGSEGV +++
Viewing smart info is OK (smartctl /dev/sda -dmegaraid,24 -a).
Running self-test on SATA disk on the same system is OK.
The problem is reproducible with 2.6.32 and 2.6.36 kernels.
I understand that linux-ide@vger.kernel.org is not right place to ask
this question, but I believe that somebody here can point the way to
resolve the problem.
