-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:

-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

-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
-REPORTER: see link below
-LINK: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=208964
-NOTE: Problem seems to affect kernel 2.4.21 only.
-
-
-SYSTEM: Promise IDE-controllers and perhaps others also
-PROBLEM: System freezes under heavy load, perhaps when running SMART commands
-REPORTER: Mario 'BitKoenig' Holbe Mario.Holbe@RZ.TU-Ilmenau.DE
-LINK: http://groups.google.de/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8&selm=1wUXW-2FA-9%40gated-at.bofh.it
-NOTE: Before freezing, SYSLOG shows the following message(s)
- kernel: hdf: dma timer expiry: dma status == 0xXX
- where XX is two hexidecimal digits. This may be a kernel bug
- or an underlying hardware problem. It's not clear if
- smartmontools plays a role in provoking this problem. FINAL
- NOTE: Problem was COMPLETELY resolved by replacing the power
- supply. See URL above, entry on May 29, 2004 by Holbe. Other
- things to try are exchanging cables, and cleaning PCI slots.
-
-FREEBSD
--------
-
-[No problem reports yet.]
-
-
-SOLARIS
--------
-
-[No problem reports yet.]
-
-
-CYGWIN and WINDOWS
-------------------
-
-SYSTEM: Any Windows NT4, 2000 or XP system.
-PROBLEM: Use of undocumented system calls for IDE/ATA read log
- (smartctl -l, --log, -a, --all) may affect system stability.
-REPORTER: Christian Franke <smartmontools-support@lists.sourceforge.net>
-NOTE: The IOCTL call SMART_RCV_DRIVE_DATA does not support
- ATA_SMART_READ_LOG_SECTOR on NT4/2000/XP. The Win32
- implementation of smartctl/smartd uses undocumented
- and possibly buggy system calls for this purpose:
- NT4: IOCTL_SCSI_PASS_THROUGH with undocumented pseudo SCSI
- command SCSIOP_ATA_PASSTHROUGH (0xCC).
- 2000/XP: Undocumented IOCTL_IDE_PASS_THROUGH.
-
-
-DARWIN
-------
-
-SYSTEM: Any system before Tiger
-PROBLEM: Can't switch off SMART, can't switch off auto-save, can't run
- short tests.
-REPORTER: Geoff Keating <geoffk@geoffk.org>
-NOTE: There's a bug in the system library: when you ask it to
- do any of these things, it does the inverse (switches on,
- runs extended tests). Radar 3727283.
-
-SYSTEM: All known systems
-PROBLEM: When drive is asleep, SMART commands fail
-REPORTER: Geoff Keating <geoffk@geoffk.org>
-NOTE: You can prevent the drive from sleeping by saying
- pmset -a disksleep 0
- or by unchecking the 'Put the hard disk(s) to sleep when possible'
- checkbox in the Energy Saver preferences. Radar 4094403.
