Hi all,

I see the following message in my kernel log:

dmi type 0xB1 record - unknown flag

This is on a Dell Optiplex 9020 workstation. I see the message comes
from:

static void __init read_dmi_type_b1(const struct dmi_header *dm,
                                    void *private_data)
{
	(...)
        switch (((*(u32 *)d) >> 9) & 0x03) {
        case 0x00:
                printk(KERN_INFO "dmi type 0xB1 record - unknown flag\n");
                break;

What is the value of this message? Is there anything which needs to be
done to properly support such systems?

Thanks,
