First note that every field delimiter character matters to the cut utility, so the output from the command:
Code:
cut -d" " -f1-6,8- filename

(with your sample input) is:
Code:
1:  010 0xad45  sp1  11:29:51.498583949 500249144  Event1 rst bcfe jhv rgc
456:  010 0xadb  sp2  11:29:51.498600605     4464  Event0abcrd adabc aasd
45:  010 0x10 sp0 - 11:29:51.498614165    13560   Back adxca msg to end
4969:  010 0xjill  spx  11:29:51.498632789    18624  global service desk to the rescue

which is not even close to what you said you wanted when the 7th field is deleted.

I can produce output similar to what you said you want (although the number of spaces are different on some lines around the deleted field) with the vi commands:
Code:
:g/\([^[:space:]]*[[:space:]]*[^[:space:]]*[[:space:]]*[^[:space:]]*[[:space:]]*[^[:space:]]*[[:space:]]*[^[:space:]]*[[:space:]]*[^[:space:]]*[[:space:]]*\)[^[:space:]]*/s//\1/

to remove the 7th field, and
Code:
:g/\([^[:space:]]*[[:space:]]*[^[:space:]]*[[:space:]]*[^[:space:]]*[[:space:]]*[^[:space:]]*[[:space:]]*[^[:space:]]*[[:space:]]*[^[:space:]]*[[:space:]]*\)\([^[:space:]]*\)/s//\2 \1/

to move the 7th field to the start of the line.

rmalloc_wait

rmalloc_wait(9F)					   Kernel Functions for Drivers 					  rmalloc_wait(9F)

NAME

       rmalloc_wait - allocate space from a resource map, wait if necessary

SYNOPSIS

       #include <sys/map.h>
       #include <sys/ddi.h>

       unsigned long rmalloc_wait(struct map *mp, size_t size);

INTERFACE LEVEL

       Architecture independent level 1 (DDI/DKI).

PARAMETERS

       mp      Pointer to the resource map from which space is to be allocated.

       size    Number of units of space to allocate.

DESCRIPTION

       The rmalloc_wait() function requests an allocation of space from a resource map. rmalloc_wait() is similar to the rmalloc(9F) function with
       the exception that it will wait for space to become available if necessary.

RETURN VALUES

       The rmalloc_wait() function returns the base of the allocated space.

CONTEXT

       This function can be called from user, interrupt, or kernel context. However, in most cases rmalloc_wait() should not be called from inter-
       rupt context.

SEE ALSO

       rmalloc(9F), rmallocmap(9F), rmfree(9F), rmfreemap(9F)
