The following are reports of serious problems (eg system lockup) which
were due to smartmontools. There are DARWIN, LINUX, FREEBSD, SOLARIS
and WINDOWS sections below.
LINUX

You may also wish to search the linux-kernel mailing list for problem
reports concerning smartmontools. Here is the URL:
http://groups.google.com/groups?as_q=smartmontools&safe=images&ie=UTF-8&oe=UTF-8&as_ugroup=linux.kernel&lr=&num=100&hl=en
SYSTEM: Any system with USB ports and USB storage devices
PROBLEM: Using smartd/smartctl on USB "SCSI" storage devices can cause kernel hang
REPORTER: see link below
LINK: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=107615
NOTE: USB storage devices are handled as SCSI devices by the kernel. But many of these
devices do not comply with SCSI specs, and can cause the kernel to hang.
Avoid using smartd/smartctl on these devices (they don't do SMART anyway).
In particular, the use of smartd DEVICESCAN in /etc/smartd.conf can cause
these devices (typically represented by /dev/sda or /dev/sdb) to hang, and
the kernel to lock up.
FIXED: This problem should be fixed in smartmontools-5.25 and greater.
SYSTEM: Intel 875WP1-E motherboard with SATA drives on motherboard's SATA ports
PROBLEM: smartd makes NTP time drift
REPORTER: nohez@cmie.com
LINK: http://groups.google.de/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8&safe=off&selm=Pine.LNX.4.33.0310111545530.1047-100000%40venus.cmie.ernet.in.lucky.linux.kernel
NOTE: When using SATA disks, linux kernel k_smp-2.4.21-108 (SMP because
of hyper-threading) and xntp-4.1.1-177, the server time went
out of sync with system time. Problem goes away when SATA
disks removed.
SYSTEM: Dell servers using AACRAID (SCSI)
PROBLEM: Locked up, needed to be rebooted
REPORTER: drew@eastvan.bc.ca
LINK: http://sourceforge.net/mailarchive/forum.php?thread_id=1311313&forum_id=12495
SYSTEM: Box with Promise 20265 IDE-controller (pdc202xx-driver) and > 2.4.18 kernel with ide-taskfile support
PROBLEM: Smartctl locks system solid when used on /dev/hd[ef].
REPORTER: Georg Acher <acher@in.tum.de>
LINK: http://sourceforge.net/mailarchive/forum.php?thread_id=1457979&forum_id=12495
NOTE: Lockup doesn't happen with 2.4.18 kernel, and doesn't affect /dev/hd[a-d]
This appears to be a problem with the pdc202xx-driver and has been reported
to the pdcx maintainers. If you enable the Promise-BIOS (ATA100-BIOS) then
everything will work fine. But if you disable it, then the machine will hang.
SYSTEM: Box with Promise 20262 IDE-controller
PROBLEM: Smartctl locks system solid
REPORTER: Ben Low <ben@bdlow.net>
LINK: http://sourceforge.net/mailarchive/message.php?msg_id=5074201
NOTE: Similar to previous report: Promise Ultra66 2-port card (20262) which, with
linux 2.4.20, suffers from the lockups reported above. But it was
impossible to enable the Promiste BIOS. A kernel patch is referenced
to fix the problem.
SYSTEM: Promise 20265 IDE-controller
PROBLEM: Smartctl locks system solid when used on CDROM/DVD device
