Grepping for SYS_ERR_DEPTH_EXCEEDED results in:<br>
kernel/capabilities.c-618- // If lookup exceeded expected depth then table is malformed<br>
kernel/capabilities.c-619- if (bits_resolved > vbits) {<br>
kernel/capabilities.c-620- debug(SUBSYS_CAPS, "caps_lookup_slot: Lookup exceeded valid bits\n"<br>
kernel/capabilities.c-621- "Cnode bits = %u, guard size = %u, valid bits = %u\n",<br>
kernel/capabilities.c-622- cnode_cap->u.cnode.bits, cnode_cap->u.cnode.guard_size,<br>
kernel/capabilities.c-623- vbits);<br>
kernel/capabilities.c:624: return SYS_ERR_DEPTH_EXCEEDED;<br>
kernel/capabilities.c-625- }<br>
<br>
I'm wondering whether this has something to do with the patch that you<br>
applied... I'm guessing that using BIOS allocation did not help.<br>
<br>
It might be worth enabling the debug for the caps system. Can you please<br>
replace the corresponding line in menu.lst with:<br>
<br>
module /x86_64/sbin/cpu loglevel=5 logmask=0x40<br>
<br>
And send us the debug messages?<br>
<br>
