Hi Andrew,

-mm4 won't mount my ext3 root device whereas -mm3 will. Presumably this is 
some byproduct of the dev_t patches.

VFS: Cannot open root device "302" or hda2.
Please append correct "root=" boot option.
Kernel Panic: VFS: Unable to mount root fs on hda2.

One possible explanation is that I have devfs compiled into my kernel. I do 
not, however, have it automatically mounting on boot. It overlays /dev (which 
is populated with original style device nodes) after INIT has loaded.

Perhaps there is some other procedure I must complete before I can use 32bit 
dev_t?

Amazingly idiotic typo.  And yes, it gets hit only if devfs is configured.

No. As I said, I mount /dev with mount -t devfs devfs /dev in a sysinit 
bootscript. Whether it's in the kernel or not shouldn't make any difference. 
Maybe I just need to reissue LILO after booting the 32bit dev_t kernel?

I'll try that, thanks. But I have this in lilo.conf:

boot=/dev/discs/disc0/disc
root=/dev/discs/disc0/part2

/dev/discs is indeed a symlink, but it should be resolved when LILO is 
installed, i.e., prior to the reboot. Why has this behaviour changed?

Cheers,
Alistair.

Changing it as per your suggestion makes no difference. I still cannot boot, 
and the error is identical.

Disregard my last email.

Thanks for that. It's working fine now.

I don't think this has to do with ext3, since my root xfs partition can't be 
mounted either.

same over here, except replace hda2 with sda3 and (302 with 803 of couse).

I disabled mount at root and created some device nodes, but it still doesn't 
work, befor that I had pure devfs. Reading the config help for devfs says 
it's obsoleted, and stripped down to a "bare minimum to not break anyting". 
Does that "bare minimum" include hard disks?

Do you use devfsd ? 

I had to specify root like this :
root=/dev/ide/host0/bus0/target0/lun0/part5  then it worked just fine.

You mean it breaks the XFree driver?  Is it just a matter of editing
XF86Config to tell it the new protocl name?

Either way, it looks like a change which should be reverted?

It breaks the event device auto detection, which works by parsing
/proc/bus/input/devices. The protocol name is hard coded so you can't
just change the XF86Config file.

> Either way, it looks like a change which should be reverted?

I think the new protocol name is better, so why not just fix the X
driver instead. Here is a fixed version:

Ouch? This is just an information string, it is not supposed to be used
anywhere except printks etc ... I really HOPE nobody is parsing these
strings.

Before the patch, the input_dev.name string said

"Synaptics Synaptics Pad", which kind of didn't make much sense.

Since it's a concatenation of protocol, vendor and device names, it
now says

"SynPS/2 Synaptics Pad", which sounds a bit better.

> Either way, it looks like a change which should be reverted?

If it breaks anything, that needs to be fixed in what it broke, because
nothing should depend on this. If it does, then that's a big bug.

I'd suggest the driver either checks the BUS/VENDOR/DEVICE ids or the
bitfields for the pad, not the name. Names are unreliable ...

Re: 2.6.0-test5-mm4 boot crash

[Helge Hafting]

test5-mm4 crashed during RAID-1 autodetection and setup.
It got as far as:
md: created md0
md: bind<hda1>
md: bind<hdb1>
md: running: <hdb1><hda1>

After this, I usually get this (from test5-mm3 dmesg):
raid1: raid set md0 active with 2 out of 2 mirrors
md: ... autorun DONE.
VFS: Mounted root (ext2 filesystem) readonly.

Instead, I got the dump at the end of this message.
I'm using devfs and Viro's compile fix for devfs in mm4.
The root fs is on raid-1, the raid-1 gets autodetected.

The kernel has no module support, and no initrd.

Here's the dump:

Unable to handle null pointer deref at virtual address 00000000

Oh, boy...  OK, I see what happens and it's _ugly_.  md_probe() is misused
there big way.  The minimal fix is to revert the cleanup in md_probe() -
replace
	int unit = *part;
with
	int unit = MINOR(dev);


However, that is crap solution.  The problem is that md_probe() is called
directly with bogus arguments - not only part is NULL (which triggers the
oops), but dev (which is supposed to be dev_t value) is actually mdidx(mddev).

Cleaner fix follows, but we really need to get the situation with gendisk
allocations into the sane shape there.  Sigh...

OK, this is now implemented in version 0.11.5, which I just uploaded
to my web site. This version also adds support for the new events
ABS_TOOL_WIDTH, BTN_TOOL_FINGER, BTN_TOOL_DOUBLETAP and
BTN_TOOL_TRIPLETAP.
