On attempting to boot this kernel, I get the following just before init:
Kernel panic: VFS: Unable to mount root fs on 03:05

2.5.67 base works fine. I discovered that reverting the following 
patches allows me to boot. I can increase the granularity of my search 
if nothing comes immediately to mind:

aggregated-disk-stats.patch
dynamic-hd_struct-allocation-fixes.patch
dynamic-hd_struct-allocation.patch

I reverted the aggregated-xx patch because it depends on the dynamic 
hd_struct work in a single line;

+               struct hd_struct *hd = gp->part[n];

Therefore it may not be this patch that is the source of the problem, 
but I backed it out anyway.

Cheers,
Alistair Strachan.

Ah, good detective work, thanks.  It looks like the hd_struct dynamic allocation
patch has broken devfs partition discovery somehow.

Thanks.. I am going to look now. Must have broken something in devfs.

Okay !! My bad. 

Here is the patch for 2.5.67-mm1. Could you try and let me know ?

Sorry for the delay, I've only just woken up. I applied the patch, it

        char devname[16];

        if (p[part-1]->de)

With that in place, it compiled without warning and the machine now 
boots with the dynamic hd_struct work + aggregate stats patch.

Thanks for your time.

Re: 2.5.67-mm1

[Helge Hafting]

Devfs fails to find all partitions with 2.5.67-mm1, plain 2.5.67 is fine

I have 2 scsi disks, and 2.5.67-mm1 find only some of the partitions
when I boot.  Below is ls -l listings for /dev/discs/disc0 and
/dev/discs/disc1.  Note the missing stuff - linux wasn't at all 
happy when the device for /usr couldn't be found at boot time.
Running cfdisk showed that the partitions were there though.

Is your keyboard PS/2 or PC-AT-like, or something else?

Interesting.  If I force that register IRQ 12 to fail, I just get this
one time:

i8042.c: Can't get irq 12 for AUX, unregistering the port.
serio: i8042 AUX port at 0x60,0x64 irq 12

I guess that's due to my early kbd init patch.
So why do you have i8042 configured into your kernel?

The loop doesn't terminate?  Do you get the same message (above)

task_vsize() mysteriously appeared on my profiles. This should remove

Hi,

This does not boot here.  I loop with the following message.

irq 12 is used (correctly) by my 20267 ide card.  My mouse is

This is fine. The changelog comment doesn't look right though. It says
it's inferrable from slabinfo; it's meant to measure the number of
reverse mappings performed, or aggregate faulted-in virtualspace on the
system, or the number of PTE's pointing at userspace data.

The internal fragmentation within slabs is a separate notion.
pte_chains carry more than a single pointer, so the net utilization and
internal fragmentation of the things allocated can be computed from
nr_reverse_maps/(#pte_chains * NR_PTE), and is very different from the
internal fragmentation of slabs (there is no relationship whatsoever).

This stuff has been disturbed on several occasions, and effectively
lost whatever meaning it had left after PG_direct anyway, regardless
of who changed it to mean what, as the accounting was never adjusted to
remove PG_direct reverse mappings (the actions, not any kind of space)
from the count due to not being able to identify the notion that would
be measured by it. nr_shared_reverse_maps? It's dead, kill it.
