[PATCH] change acquire/release_console_sem() to console_lock/unlock()
the -rt patches change the console_semaphore to console_mutex.
so a quite large chunk of the patches changes all
acquire/release_console_sem() to acquire/release_console_mutex()
this commit makes things use more neutral function names
which dont make implications about the underlying lock.
the only real change is the return value of console_trylock
which is inverted from try_acquire_console_sem()

CentOS 4.2 x86_64
...ntOS 4.2 x86_64 to boot on some
of them in SMP mode (UP works fine). After the installation of CD, it
boots up but kernel panics with the following error:
Badness in i8042_panic_blink at drivers/input/serio/i8042.c:992
This is the call trace:
apic_timer_interrupt+133
vgacon_cursor+0
oops_end+64
release_console_sem+369
error_exit+0
:scsi_mod:scsi_delete_timer+19
:3w_9xxx:twa_interrupt+1323
do_IRQ+197
mwait_idle+86
cpu_idle+26
The Uni processor works fine.
I tried the SMP kernel from Fedora Core 4 x86_64 which works fine as
well. Any idea what's going on here? I've already tried disabling as
many...

xen: Make hvc0 the preferred console in domU
This makes the Xen console just work. Before, you had to ask for it
on the kernel command line with console=hvc0

2.6.31 xenified kernel - not ready for production
Hi,
I just want to know if somebody use 2.6.31.4 xenified kernel (aka
OpenSUSE) in production?
We have been testing it on new Nehalem Xeon server for few weeks w/o
any problem.
But as soon we tried it on production machine - after several
production domUs started - hard OS failure.
We had to switch back to 2.6.18.8 - xen stock kernel.

Newbie questions -- is OCFS2 what I even want?
Dear Sirs and Madams,
I run a small visual effects production company, Hammerhead Productions.
We'd like to have an easily extensible inexpensive relatively
high-performance
storage network using open-source components. I was hoping that OCFS2
would be that system.
I have a half-dozen 2 TB fileservers I'd like the rest of the network to see
as a single 12 TB disk, with the aggregate

dom0 unable to launch domU
Hi,
I have a problem with a dom0 which is unable to launch my domU : all my
dom0 are Debian Lenny amd64 with Debian kernel 2.6.26-2-xen-amd64 and
xen-hypervisor-3.2-1-amd64. Then all domU (PV) are Debian Lenny amd64
too, with vanilla kernel 2.6.29.6.
So, this new dom0 can''t launch any domU which are working on an other
dom0. Software is same on both dom0, and hardware is near the

[PATCH 0/5] xen pvfb: Para-virtual framebuffer, keyboard and pointer driver updates
This is an update to the Linux part of the Xen PVFB. Linux Xen PVFB
is a pair of Xen para-virtual frontend device drivers:
drivers/video/xen-fbfront.c provides a framebuffer, and
drivers/input/xen-kbdfront provides keyboard and mouse. Their
backends run in dom0 user space.
Parts in this patch series:
1. Enable Xen console by default in domU
2. Pointer z-axis (mouse wheel) support
3. Module
