bad LUN and bad target number startup problem

Hello

Since few time, when my laptop boots I have some strange lines just after uevent :

bad LUN
bad target number (1:0)
....
bad target number (7:0)

They are in the everything.log and dmesg. Here you have the relevant part of the dmesg output, lspci and lsusb (it seems to be related with some SCSI removable disk...):

I can boot, but something seems to be broken or at least not very clean (and it seems that my boot is a bit longer). Is there a way to reset/reconfigure target numbers ? (no idea of what is that... I googled without success).

All my usb seem to work with keyboard, mouse and usb key... as the SD card reader. I also have something called HG duo (sony vaio laptop) but I don't have this kind of card so I can't test it.

The problem occured with the kernel26_mainline (3.0), but also with 2.6.39 and now with linux3.0 in core...

Does anybody has an idea on what's going on ? (and how to fix it...)

Merci!!

Re: bad LUN and bad target number startup problem

LUN stands for Logical Unit Number.  In dmesg lines like

sd 6:0:0:0 ...

the first number is Host, the second number is Channel, the third number is ID (aka Target), and the fourth number is LUN.

AFAIK LUN is only used in SCSI protocol.  For example, in my box with two SATA drives attached to onboard SATA ports, the drives show up as 0:0:0:0 and 1:0:0:0.  My IDE CD-ROM shows up as 2:0:1:0 (the Target # is 1 because it's slave). So I find it odd that you are seeing 6:0:0:0 and 6:0:0:1.  I think it's likely that you've got some bad (or badly acting) hardware.

For starters a 'plain-language' description of the storage devices attached to your machine (type and connection) would be helpful.

In addition, post the output of fdisk -l and cat /proc/scsi/scsi and the contents of /etc/fstab.

Re: bad LUN and bad target number startup problem

The problem is related to the 'Generic SD - MMC' and/or 'Generic Memory stick'. At first I thought they might be one device acting strangely, but now that doesn't seem to be the case.  The best I can suggest is to try with just one of them connected, and see if the errors persist.  When you're up, run cat /proc/scsi/scsi again, and fdisk -l, this time as root or using sudo.  Then do the same with the other device.

Re: bad LUN and bad target number startup problem

My laptop only has few weeks.... If it is possible to not destroy it.... (I'm not very comfortable with the hardware part, and I think that I will lost the warranty if I open this part).
But I found an option in the bios to disable the memory card reader (both I guess... or maybe there are 2 slots but only one thing to plug), and the bad target number message disappear.

With memory cards disabled :

fdisk -l

Any idea ? I will try to boot on windows to see if there is any problem...

[edit]: no problem with windows : no strange messages, no strange icon in device manager.. It may be a software problem and not a hardware one ?

Re: bad LUN and bad target number startup problem

I also have a very similar problem to olsman037, and I can confirm that it seems to be a problem with the SD card reader: my /proc/scsi/scsi:

Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: ATA      Model: TOSHIBA MK7575GS Rev: GT00

  Vendor: Generic- Model: xD/SD/M.S.       Rev: 1.00
  Type:   Direct-Access                    ANSI  SCSI revision: 02

and the relevant portion of dmesg:

[    5.681887] sd 6:0:0:0: Attached scsi generic sg2 type 0
[    5.681996] sd 6:0:0:0: [sdb] Attached SCSI removable disk

[    5.851481] Bad target number (6:0)
[    5.928092] Bad target number (7:0)

I have no prior experience of SD card readers under linux, but it seems quite odd that it thinks it's "removable disk" sdb, doesn't it?
Also, it seems that lscpi fails to recognise the device, returning it as

13:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. Device 5209 (rev 01)

again very similar to olsman037's lspci

It would be great if someone who understands to some extent the problem could help on this one. Is it a bug? Should it be reported?

Re: bad LUN and bad target number startup problem

Filed a bug in Kernel Bugzilla:
https://bugzilla.kernel.org/show_bug.cgi?id=42640

Btw, blacklisting the rts_pstor kernel module gets rid of the errors but also disables the card reader of course. Might be a workaround for those who don't use the reader anyway.

Re: bad LUN and bad target number startup problem

Well, since no one could 'fix' this, can anyone suggest a way to keep this error from posting to the terminal on boot? It looks critical and its quite tacky imho. Perhaps we can simply report [in red lettering] that no removable media is present instead of some random LUN message? I don't use the card reader but I plan to, and blacklisting the kmod seems like something I might forget!

If you know of a way to recompile kmods feel free to post link to the TUT! I really don't have time to wait for some kdev to get off his t-ass-k list to do something he should have done right the first time (in other words I'm not holding my breath for the second coming.)


systemd has its advantages; of these the most damaging are: corporatization, security bottlenecks, control obfuscation, and micro-managed forward compatibility pitfalls. Free Software meets Dictatorship. What a maroon.

Re: bad LUN and bad target number startup problem

From the developer: "We will fix the issue to printing "bad lun" or "bad target number" during boot, in our next submission to the kernel staging tree.".

It is also possible to download the source code from the Realtek site, comment out the lines printing the 'bad lun' and 'bad target number' messages, and then compile the driver yourself.  The file with the source code is "rtsx.c".  Lines 530,531 en 536,537 in the version I downloaded.  Compilation instructions are in the README after extracting the driver.
