Public bug reported:
Binary package hint: linux-image-2.6.24-19-openvz
Hi,
I ran into a very annoying kernel bug. I know that there are several
similar bug reports, but none with the openvz-kernel.
Under heavy IO the machine just freezes and the console is flooded with
soft lockup messages:

In fact the server is still pingable, but not usable :-(
Configuration:
Server: Sun Fire X4240
CPUs: 2x Quad-Core Processor 2356
RAM: 32 GByte RAM
Latest BIOS.
OS: Ubuntu 8.04.1 LTS Server
Kernel: linux-image-2.6.24-19-openvz (2.6.24-19.41)
Using different boot options, like "noapic", "highres=off" or "nohz=off"
was unsuccessful.
I cannot try the latest kernel 2.6.27 cause I need an openvz-kernel.
Maybe someone is able to fix this!
Thanks!
Alexander
