panic due to lost vnode flag

[Matthias Drochner <M.Drochner%fz-juelich.de@localhost>]

Hi -
I'm getting a diagnostic panic occasionally, when I
do some compilations cuncurrently:
kernel diagnostic assertion "vp->v_iflag & VI_TEXT" failed:
file "../../../../kern/exec_subr.c", line 162

The stacktrace is:
#9  0xc045875d in panic (
    fmt=0xc06efe74 "kernel %sassertion \"%s\" failed: file \"%s\", line %d")
    at ../../../../kern/subr_prf.c:293
#10 0xc05a1709 in __kernassert (t=0xc067df6a "diagnostic ",
    f=0xc06922c3 "../../../../kern/exec_subr.c", l=162,
    e=0xc06922ad "vp->v_iflag & VI_TEXT")
    at ../../../../../../lib/libkern/__assert.c:50
#11 0xc021395e in vmcmd_map_pagedvn (l=0xcd85e800, cmd=0xcec3a204)
    at ../../../../kern/exec_subr.c:162
#12 0xc0303c37 in execve1 (l=0xcd85e800,
    path=0xbb993484 <Address 0xbb993484 out of bounds>, args=0xbb9934dc,
    envs=0xbb993604, fetch_element=0xc030302e <execve_fetch_element>)
    at ../../../../kern/kern_exec.c:803
#13 0xc0304964 in sys_execve (l=0xcd85e800, uap=0xcd7a4d00, retval=0xcd7a4d28)
    at ../../../../kern/kern_exec.c:436
#14 0xc046dfd1 in syscall (frame=0xcd7a4d48) at ../../../../sys/syscallvar.h:61

This is i386/-current on a dual-core box.
Any ideas?

best regards
Matthias
