! 6: The following are reports of serious problems (eg system lockup) which
! 7: were due to smartmontools. There are DARWIN, LINUX, FREEBSD, SOLARIS
! 8: and WINDOWS sections below.
! 9:
! 10:
! 11: LINUX
! 12: -----
! 13:
! 14: You may also wish to search the linux-kernel mailing list for problem
! 15: reports concerning smartmontools. Here is the URL:
! 16: 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
! 17:
! 18: SYSTEM: Any system with USB ports and USB storage devices
! 19: PROBLEM: Using smartd/smartctl on USB "SCSI" storage devices can cause kernel hang
! 20: REPORTER: see link below
! 21: LINK: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=107615
! 22: NOTE: USB storage devices are handled as SCSI devices by the kernel. But many of these
! 23: devices do not comply with SCSI specs, and can cause the kernel to hang.
! 24: Avoid using smartd/smartctl on these devices (they don't do SMART anyway).
! 25: In particular, the use of smartd DEVICESCAN in /etc/smartd.conf can cause
! 26: these devices (typically represented by /dev/sda or /dev/sdb) to hang, and
! 27: the kernel to lock up.
! 28: FIXED: This problem should be fixed in smartmontools-5.25 and greater.
! 29:
! 30:
! 31: SYSTEM: Intel 875WP1-E motherboard with SATA drives on motherboard's SATA ports
! 32: PROBLEM: smartd makes NTP time drift
! 33: REPORTER: nohez@cmie.com
! 34: 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
! 35: NOTE: When using SATA disks, linux kernel k_smp-2.4.21-108 (SMP because
! 36: of hyper-threading) and xntp-4.1.1-177, the server time went
! 37: out of sync with system time. Problem goes away when SATA
! 38: disks removed.
! 39:
! 40:
! 41: SYSTEM: Dell servers using AACRAID (SCSI)
! 42: PROBLEM: Locked up, needed to be rebooted
! 43: REPORTER: drew@eastvan.bc.ca
! 44: LINK: http://sourceforge.net/mailarchive/forum.php?thread_id=1311313&forum_id=12495
! 45:
! 46:
! 47: SYSTEM: Box with Promise 20265 IDE-controller (pdc202xx-driver) and > 2.4.18 kernel with ide-taskfile support
! 48: PROBLEM: Smartctl locks system solid when used on /dev/hd[ef].
! 49: REPORTER: Georg Acher <acher@in.tum.de>
! 50: LINK: http://sourceforge.net/mailarchive/forum.php?thread_id=1457979&forum_id=12495
! 51: NOTE: Lockup doesn't happen with 2.4.18 kernel, and doesn't affect /dev/hd[a-d]
! 52: This appears to be a problem with the pdc202xx-driver and has been reported
! 53: to the pdcx maintainers. If you enable the Promise-BIOS (ATA100-BIOS) then
! 54: everything will work fine. But if you disable it, then the machine will hang.
! 55:
! 56:
! 57: SYSTEM: Box with Promise 20262 IDE-controller
! 58: PROBLEM: Smartctl locks system solid
! 59: REPORTER: Ben Low <ben@bdlow.net>
! 60: LINK: http://sourceforge.net/mailarchive/message.php?msg_id=5074201
! 61: NOTE: Similar to previous report: Promise Ultra66 2-port card (20262) which, with
! 62: linux 2.4.20, suffers from the lockups reported above. But it was
! 63: impossible to enable the Promiste BIOS. A kernel patch is referenced
! 64: to fix the problem.
! 65:
! 66:
! 67: SYSTEM: Promise 20265 IDE-controller
! 68: PROBLEM: Smartctl locks system solid when used on CDROM/DVD device
! 69: REPORTER: see link below
! 70: LINK: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=208964
! 71: NOTE: Problem seems to affect kernel 2.4.21 only.
! 72:
! 73:
! 74: SYSTEM: Promise IDE-controllers and perhaps others also
! 75: PROBLEM: System freezes under heavy load, perhaps when running SMART commands
! 76: REPORTER: Mario 'BitKoenig' Holbe Mario.Holbe@RZ.TU-Ilmenau.DE
! 77: LINK: http://groups.google.de/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8&selm=1wUXW-2FA-9%40gated-at.bofh.it
! 78: NOTE: Before freezing, SYSLOG shows the following message(s)
! 79: kernel: hdf: dma timer expiry: dma status == 0xXX
! 80: where XX is two hexidecimal digits. This may be a kernel bug
! 81: or an underlying hardware problem. It's not clear if
! 82: smartmontools plays a role in provoking this problem. FINAL
! 83: NOTE: Problem was COMPLETELY resolved by replacing the power
! 84: supply. See URL above, entry on May 29, 2004 by Holbe. Other
! 85: things to try are exchanging cables, and cleaning PCI slots.

! 104:
! 105: DARWIN
! 106: ------
! 107:
! 108: SYSTEM: Any system before Tiger
! 109: PROBLEM: Can't switch off SMART, can't switch off auto-save, can't run
! 110: short tests.
! 111: REPORTER: Geoff Keating <geoffk@geoffk.org>
! 112: NOTE: There's a bug in the system library: when you ask it to
! 113: do any of these things, it does the inverse (switches on,
! 114: runs extended tests). Radar 3727283.
! 115:
! 116: SYSTEM: All known systems
! 117: PROBLEM: When drive is asleep, SMART commands fail
! 118: REPORTER: Geoff Keating <geoffk@geoffk.org>
! 119: NOTE: You can prevent the drive from sleeping by saying
! 120: pmset -a disksleep 0
! 121: or by unchecking the 'Put the hard disk(s) to sleep when possible'
! 122: checkbox in the Energy Saver preferences. Radar 4094403.
