Hi,
my PB1176 doesn't boot properly in 2.6.35-rc1, it goes to this point
and hangs:
(...)
Switching to clocksource timer3
NET: Registered protocol family 2
IP route cache hash table entries: 1024 (order: 0, 4096 bytes)
TCP established hash table entries: 4096 (order: 3, 32768 bytes)
TCP bind hash table entries: 4096 (order: 2, 16384 bytes)
TCP: Hash tables configured (established 4096 bind 4096)
TCP reno registered
UDP hash table entries: 256 (order: 0, 4096 bytes)

NET: Registered protocol family 1
RPC: Registered udp transport module.
RPC: Registered tcp transport module.
RPC: Registered tcp NFSv4.1 backchannel transport module.
I bisected until I had this as the first commit causing the trouble:
commit ac1d426e825ab5778995f2f6f053ca2e6b45c622
Merge: fda0e18 a3685f0
Author: Russell King <rmk+kernel@arm.linux.org.uk>

Merge branch 'devel-stable' into devel
Conflicts:
arch/arm/Kconfig
arch/arm/include/asm/system.h
arch/arm/mm/Kconfig
This doesn't say much so I suspect it's this latter one causing it:
commit fda0e18c8a7a3e02747c2b045b4fcd2c920410b9

Any hints on how to fix this? Some PMU issue on this board
perhaps?
Yours,

Have you tried disabling CONFIG_CACHE_L2X0?

Hey it works! :-)
I suppose your latest patches will hopefully get the defconfig with
l2x0 working again in -rc2 if they're merged?

I think there is an L2 erratum (and trying to get the right workaround).
It may be triggered by commit e7c5650f6.
I'll get back on the list with a patch.

Have I missed this? My 2.6.35's and -next trees still require me to
disable the L2X0 cache on the PB1176 for it to boot.
It's a bit sad if we have a 2.6.35 which cannot even boot on this
card...
Can you send me a copy of the errata so I can look at it if
you're swamped with other stuff?
Yours,
Linus Walleij

I posted some patches couple of times but I haven't received any
comments. I'm posting another version (now only affecting the RealView
code) and cc you. If it works for you as well, I'll send it to the patch
system.

You should be able to bisect further - did bisect just give up at this
point?
Do you know which half of that merge was also tested?
