Hi,
Just got this (reproducible) kernel panic (BUG in
asm-i386/highmem.h::kmap_atomic(), the if (!pte_none(*(kmap_pte-idx)))
BUG(); triggers). It happens every time I boot and on an NFS mount do a
./configure.
I am now seeing this error during boot as well. Don't know if it is
related:

00:09.0: 3Com PCI 3c590 Vortex 10Mbps at 0xe800. Vers LK1.1.17
00:09.0: Overriding PCI latency timer (CFLT) setting of 32, new value is
248.
***INVALID CHECKSUM 002f*** phy=0, phyx=24, mii_status=0x782d
---snip---
Note that on previous kernels it says:
---snip---
PCI: Assigned IRQ 11 for device 00:09.0
3c59x: Donald Becker and others. http://www.scyld.com/network/vortex.html
00:09.0: 3Com PCI 3c905C Tornado at 0xe800. Vers LK1.1.17
phy=0, phyx=24, mii_status=0x782d
---snip---
Note the Assigned IRQ message is missing in 2.5.20. Also the 2.5.20
kernel (ACPI) decides to use PIC routing for interrupts instead of
IOAPIC as it did before. Possibly also related? - Booting with APM
instead of ACPI causes same panic as before.
Note mii-tool on 2.5.20 doesn't work, and it works on older kernels.
The decoded oops, lspci output, as well as the full dmesg from booting
2.5.20 together with my .config is below. Note this is on a 1G RAM,
Athlon Epox 8kta3 mobo, highmem enabled kernel, UP kernel.
Anyone have any ideas? Is my network card toast or the kernel? (Note
booting back into 2.4.18 still works fine.)
Best regards,
Anton

Dunno about this one. I'm seeing some (totally different) NFS funnies
at present - pagecache data on the client is coming up zeroes under
memory pressure. Trond mentioned that NFS recently went to kmap_atomic,
so there is a common thread there.

It misidentified the device. How bizarre. 3c590 is 0x10B7, 0x5900
and 3c905C is 0x10B7, 0x9200. lspci saw the 905C OK. Possibly the
PCI device table walking got broken or miscompiled. Works OK here,
as does NFS client on SMP+highmem.

Following an off-list chat with David, I believe that the appended
patch should fix the problem reported by Anton. It replaces the
obsolete km_type "KM_SKB_DATA" with an entry that the RPC layer can
use in the socket bottom half.
I'm less sure whether or not it will fix your problem, Andrew, but I'm
hoping you'll find time to give it a brief test ;-)...
Cheers,
Trond

It fixed it.
The problem was that pagecache data on the NFS client was showing
incorrect chunks of several k's of zeroes. No particuar alignment,
either. And it only happened when the machine is under page-replacement
pressure. And only when the machine has highmem.
It'd be nice to understand _why_ it fixed it. Do we know why NFS
was losing data when using KM_USER0? As far as I can see the new
and old code look pretty darn similar. Interested.

Anton's Oops showed that kmap_atomic(page, KM_USER0) is sometimes failing to
return an address, something that we cannot accept in a networking bottom
half (performance and reliability would suck if we had to delay and retry).
That indicates that something is calling kmap_atomic() and then getting
interrupted before it can call kunmap_atomic().
>From what I can see, the only other place where KM_USER0 is employed would be
in the *_highpage() helper routines in include/linux/highmem.h. These
routines are used in various places, but are usually not protected against
(soft and hard) interrupts or kernel pre-emption. Could it be that the latter
is what is causing trouble?

That would make sense as any user of kmap_atomic() could be preempted at
any time. And this is definitely something we should keep in mind for the
future. Perhaps we should even go as far to disable preemption in
kmap_atomic() and reenable it in kunmap_atomic()? The atomic kmaps are
usually only done in critical sections which will execute for a short
amount of time so disabling preemption should be ok.
However, I had the preemptible option disabled in the kernel I reported the
Oops on, so it can't be responsible for this particular case.
Best regards,
Anton

Any sort of interrupt whatsoever would be enough to cause a problem
here. It is enough of a condition to allow the sunrpc code to
run.
This has nothing specific to do with preemption, although the fact
that KM_USER0 usage does not block preemption is worrysome.

Duh. Of course you are right...
...and that alone suffices to justify the patch.
