Hello Herbert,

I install a second vserver on my parisc-linux box and also updated a bit
kernel stuff as this new year borns with a new kernel ;-).

All seems to works fine with "k-2.6.15 + vs-2.1.0.1 + util-verser-0.30.209" on
this system with the up kernel kernel build ;-)

Unfortunately the system BUG() with the same kernel src but build for a smp
system (as this machine has actualy 2 cpu ;-) ); here is the console message:
BUG: soft lockup detected on CPU#0!

 RP(r2): do_wait+0xe4/0xf98

which, in short, means that the bug was dtected while do_wait() was calling
_read_lock()?

This crash occures a short time after I boot the system with this kernel and I
started manualy my new (vps) guest ;-(
                                        

(oth the knernel k-2.6.15-pa0 alone seems to works fine:
I rebuild the kernel from scratch and uptime is now about 6h, though)

The VSP kernel config options are:
[...]
CONFIG_VSERVER=y
CONFIG_VSERVER_SECURITY=y
CONFIG_VSERVER_LEGACYNET=y

#
# Linux VServer
#
CONFIG_VSERVER_LEGACY=y
# CONFIG_VSERVER_LEGACY_VERSION is not set
CONFIG_VSERVER_DYNAMIC_IDS=y
# CONFIG_VSERVER_NGNET is not set
CONFIG_VSERVER_COWBL=y
CONFIG_VSERVER_PROC_SECURE=y
# CONFIG_VSERVER_HARDCPU is not set
# CONFIG_INOXID_NONE is not set
# CONFIG_INOXID_UID16 is not set
# CONFIG_INOXID_GID16 is not set
CONFIG_INOXID_UGID24=y

[...]

Oth it's also the first time I tested linux vserver with a smp system, though.

Any idea, suggestion?

Thanks,
    Joel
