Description Jack Tanner 2007-06-14 21:22:06 UTC
Description of problem:

On boot, after selecting the kernel from grub and before any services are
started, I get this message:

dmi_string: out of memory
dmi_save_oem_strings_devices: out of memory

There are no symptoms other than the warning messages. Here's some context from

I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the fedora kernel.


I am CC'ing myself to this bug and will try and assist you in resolving it if I can.

There hasn't been much activity on this bug for a while. Could you tell me if
you are still having problems with the latest kernel?

If the problem no longer exists then please close this bug or I'll do so in a
few days if there is no additional information lodged.


Comment 2 Jack Tanner 2007-09-16 22:52:56 UTC
Yes, this bug is still present in kernel-

Comment 3 Christopher Brown 2007-09-17 09:16:33 UTC
Hello Jack,

This is the code generating the error in question:


however there is a patch fedora carries which modifies this a little. Can you
install dmidecode and attach its output?

Hi Jack,

Looked into this a bit more. It seems the code is handling the error which would
otherwise have prevented the system from booting. This is output to indicate a
badly programmed BIOS. I wouldn't be concerned - oem strings for example are
pieces of information set into the BIOS concerning the system manufacturer, part
numbers, contact information. Yours is rather lengthy:

	String 29:                                                                 
	String 30:                                                                 
	String 31:

and if the 5 bytes indicates the maximum memory allotted then it certainly
exceeds it. My thinkpad has the following for example:

Handle 0x0029, DMI type 11, 5 bytes.
OEM Strings
        String 1: IBM ThinkPad Embedded Controller -[1RHT71WW-3.04    ]-

and thats it. Essentially, I think you can close as WONTFIX or NOTABUG (as this
is BIOS related, not kernel) but I'll leave it up to you. I cannot see a BIOS
update available for your system.


Comment 7 Jack Tanner 2007-09-18 21:40:38 UTC
Chris, thanks for your analysis. I feel like this is a kernel bug in the sense
that there's no reason for me, the user, to see a warning from the kernel that
my BIOS happens to have some OEM string that's too long. It's not like I can do
anything about it! The kernel should remain silent; all it does is alarm
innocent users.

Comment 8 Christopher Brown 2008-01-09 14:21:34 UTC

Apologies for the delay and fair point. Are you still seeing this with the
latest kernels - if so I'll get some feedback from one of the kernel maintainers.


Comment 9 Chuck Ebbert 2008-01-09 19:29:01 UTC
Fix for this is in -mm and should be merged in 2.6.25.
