Dear Scot= t and Terry,

Thank your help very much!

Whe= n I configured the 'raid0' device, I excute 'raidctl -s raid0'.

The system info:

kernel: type 12 trap, code=3D0

S= topped at InitBP+0x64: movl %eax, 0xec(%edx)

db>

I type 'trace'

there are :

InitBP(cdbccf00,cdb9296= 0,2,c1bc1500,40,0,1,0, c1cae200,c0170440,c1cb3800,9) at InitBP+0x64

................

Context switches not allowed in the deb= ugger.

db>

I have no experienc= e on kernel debug. I do not know that means what.

There is the function InitBP I modified to support Current. Could y= ou help me to check?

static void
InitBP(bp, b_vp, rw_flag= , dev, startSect, numSect, buf, cbFunc, cbArg,
    = ;   logBytesPerSector)
struct bio *bp;
struct= vnode *b_vp;
unsigned rw_flag;
dev_t dev;
RF_= SectorNum_t startSect;
RF_SectorCount_t numSect;
caddr_= t buf;
void (*cbFunc) (struct bio *);
void *cbArg;
&= nbsp;int logBytesPerSector;
{
/* bp->b_flags  &n= bsp;    =3D B_PHYS | rw_flag; */
/*bp->bio_fla= gs =3D B_CALL | rw_flag; XXX need B_PHYS here too? */

= bp->bio_bcount =3D numSect << logBytesPerSector;
= bp->bio_caller1 =3D(void *) bp->bio_bcount;
bp->bio_err= or =3D 0;
bp->bio_dev =3D dev;
bp->bio_data =3D b= uf;
bp->bio_blkno =3D startSect;
bp->bio_resid =3D= bp->bio_bcount; /* XXX is this right!?!?!! */
if (bp-&g= t;bio_bcount =3D=3D 0) {
  panic("bp->b_bcount is zero in= InitBP!!\n");
}

bp->bio_done =3D cbFunc; bp->_bio_buf->b_vp =3D b_vp;
}

If you have no spare time to do that, Could you give me your Current p= atch, I can learn and analyse the difference.
