Hi.
I use NetBSD 1.5R(2001/02/03 current) on Dynabook SS3330(Celeron 333 Mem 64MB).
If I start such applications as dd if=/dev/zero of=file , startx ,
/usr/local/mozilla/mozilla ... , then following kernel messages is shown
and then my machine is frozen.

When I used 1.5E , such problems never happended.
Then , I check memory size of dmesg , and find differnce between 1.5E and
1.5R like this:
1.5E:
total memory = 65020 KB
avail memory = 58820 KB
1.5R:
total memory = 65036 KB
avail memory = 58836 KB
Following is the dmesg when I define DEBUG_MEMLOAD in arch/i386/i386/machdep.c
addr 0x0 size 0x9fc00 type 0x1
addr 0x9fc00 size 0x400 type 0x2
addr 0xe8000 size 0x4000 type 0x1 (*)
addr 0xf0000 size 0x10000 type 0x2
addr 0x100000 size 0x3ee0000 type 0x1
addr 0x3fe0000 size 0x10000 type 0x3
addr 0x3ff0000 size 0x10000 type 0x2
addr 0x100a0000 size 0x16e00 type 0x2
addr 0x100b6e00 size 0x200 type 0x4
addr 0x100b7000 size 0x49000 type 0x2
addr 0xfff80000 size 0x80000 type 0x2
I doubt if (*) is illegal. So , I tried this patch for arch/i386/i386/machdep.c:

+ if( bim->entry[x].addr == 0xe8000)
+ {
+ printf( "skipping ...\n") ;
+ continue ;
+ }
/*

----
I avoid the problem by this patch.
In addition , the problem can also be avoided by this "fall back to former
code" patch.

bim = lookup_bootinfo(BTINFO_MEMMAP);

if (bim != NULL && bim->num > 0) {
#if DEBUG_MEMLOAD
printf("BIOS MEMORY MAP (%d ENTRIES):\n", bim->num);

mem_cluster_cnt++;
}
}
!
/*

--- 1934,1940 ----
mem_cluster_cnt++;
}
}
! #endif
/*

* former code.

But I have so poor knowledge of PC that I don't know why these patches works
and why address 0xe8000 size 0x400 type BIM_Memory memory cause the problem.
Anybody gives me hints of the reason or explains how to fix fundamentally ?
If this problem has already fixed , sorry.
