I've emailed the sym author to see if he can > give some insight. I just looked into the problem. Not have that much time this evening, btw. For now, I just see that the PCI device is getting a PCI BUS fault when trying to read from BUS the SCSI TARGET control block from memory on reselection. The physical memory address as seen from the PCI BUS that gets fault is the value of the DSA register (offset 0x10 of the register dump, little endian ordering) -> 0x00400000. The code seems to endianyze some address twice. The below minute patch should be tried. If it doesn't fix, I will try to find more time to-morrow evening for working on this problem. --- sym_hipd.c.ORIG=09Wed Nov 21 20:29:36 2001 +++ sym_hipd.c=09Wed Nov 21 20:30:05 2001 @@ -9371,7 +9371,7 @@ =09np->targtbl =3D (u32 *) sym_calloc_dma(256, "TARGTBL"); =09if (!np->targtbl) =09=09goto attach_failed; -=09np->targtbl_ba =3D cpu_to_scr(vtobus(np->targtbl)); +=09np->targtbl_ba =3D vtobus(np->targtbl); =09/* =09 * Allocate SCRIPTS areas. > > It's possible that there are hardware problems with this machine or > > the SCSI card; > > I don't believe so.
