[2.4] weird stuff in per part /proc/partition stats

[Mark <mark@asphyx.net>]

Hi,

Just compiled new kernel turned on per part. stats (for the first time) and 
noticed:

    3     0   78150744 hda 119129 782652 1696861 60150 1 0 1 0 -1 1987100 -1945640
    3     1   78148161 hda1 106701 0 106701 18520 1 0 1 0 0 18520 18520
    3    64   78150744 hdb 571 48 4634 6490 209 0 1672 4920 -1 1999300 -1994380
    3    65   78148161 hdb1 570 45 4626 6480 209 0 1672 4920 0 6700 11400

See the negative values?! I don't know about the last field, but having -1 
io's running seems kinda unlikely....

This only happens w/ the IDE disks.

[OK, before posting I googled somewhat and found some references to this 
problem. They did not mention the following though.]

Another weird thing is that the "use" & "aveq" fields for hda & hdb are
incremented and decremented (respectivly) by 1010 every second (to be clear: 
whole disk only, not the stats for hd[ab]1).

This happens while the partitions are mouted, unmounted and even when the 
disks are spinned down (by BIOS PM(?))

It's not a real problem for me but I thought I'd report it.

If you request more info pls. CC me, I'm not on the list.

Regards,
Mark.

I also tried w/out nvidia module (as it taints the kernel). (Have to admit 
vmware modules were also loaded before)... Stats still keep changing at same rate.

$ dmesg
[note: I have CONFIG_LOG_BUF_SHIFT set to 17 (128kb) but this does not seem 
complete and "dmesg | wc -c" only gives ~16K. Does dmesg not support >16K??]
