>Originator:     Tetsuya Isaki
>Release:        NetBSD 6.0_BETA/x68k
>Organization:
NetBSD
>Environment:
6.0_BETA/x68k (no uname because it cannot boot)
>Description:
Because mboot which is primary boot loader on HDD is corrupted,
6.0_BETA/x68k can't boot from HDD.

Here is a disassemble source of __asm() of IOCS_S_READEXT()
inline function.  trap#15 with %d0=#245, %d1=#38 is
X68000's SCSI IOCS (service call) _S_READEXT.  For this call
%d4 should contain SCSI ID, but %d4 = %d3 = %d6 = (8>>size)??
in this asm.  Therefore this service call fails and mboot will
exit.

 1ac:   7c08            moveq #8,%d6
 1ae:   e8a6            asrl %d4,%d6          ; %d6 <- (8>>size)
 1b0:   48e7 1c00       moveml %d3-%d5,%sp@-
 1b4:   2400            movel %d0,%d2
 1b6:   2606            movel %d6,%d3
 1b8:   2803            movel %d3,%d4         ; %d4 <- %d3 <- %d6
 1ba:   2a04            movel %d4,%d5
 1bc:   227c 0000 2400  moveal #9216,%a1
 1c2:   7226            moveq #38,%d1
 1c4:   203c 0000 00f5  movel #245,%d0
 1ca:   4e4f            trap #15

The source of the same place of NetBSD 5.1 are as follows:

 13c:   7008            moveq #8,%d0
 13e:   e6a0            asrl %d3,%d0          ; %d0 <- (8>>size)
 140:   48e7 1c00       moveml %d3-%d5,%sp@-
 144:   2404            movel %d4,%d2
 146:   2600            movel %d0,%d3         ; %d3 <- (8>>size)
 148:   2805            movel %d5,%d4         ; %d4 <- %d5
 14a:   2a03            movel %d3,%d5
 14c:   227c 0000 2400  moveal #9216,%a1
 152:   7226            moveq #38,%d1
 154:   203c 0000 00f5  movel #245,%d0
 15a:   4e4f            trap #15

>How-To-Repeat:
Install 6.0_BETA/x68k on 'all zero-cleaned' HDD
and reboot from sysinst.
>Fix:
No, at present.

Subject: PR/46293 CVS commit: src/sys/arch/x68k/stand/mboot
Date: Thu, 5 Apr 2012 12:01:37 +0000

 Module Name:	src
 Committed By:	isaki
 Date:		Thu Apr  5 12:01:37 UTC 2012

 Modified Files:
 	src/sys/arch/x68k/stand/mboot: Makefile mboot.c

 Log Message:
 Use common library libiocs.a.  suggested by tsutsui@.
 o Originally, mboot had an IOCS_S_READEXT() inline function but
   its expansion corrupted (from somewhere after branching netbsd-5).
   This solves PR#46293 by using the common library.
   This problem was reported by Y.Sugahara at NetBSD booth at
   Open Source Conference (OSC) 2012 Ehime in March.
 o As a side effect, it also correct the different problem that
   IOCS_S_READ() calls _S_READEXT not _S_READ.
 Should be pulled up to netbsd-6.

 mboot now depends on libiocs. noticed by tsutsui@.
