The i386 bootlaoder fails as it loads a 4442957-byte kernel, /netbsd, from
my FFS filesystem on /dev/wd0e, printing 'read text: Input/output error'.
The same bootloader loads the kernel just fine if I gzip it (/netbsd.gz,
2071303 bytes).

The bootloader can also load and boot a smallish (<3MB) *uncompressed*
kernel that I built for a Soekris board.

I am using NetBSD-current (4.99.1) sources.  I last updated within the
last month or two.  It doesn't look like there have been significant
changes to the i386 bootloader since.

The boot medium is a CompactFlash card.  Here is the disklabel on
the card,

# disklabel wd0
# /dev/rwd0d:
type: SCSI
disk: sandisk64
label: 
flags:
bytes/sector: 512
sectors/track: 32
tracks/cylinder: 8
sectors/cylinder: 256
cylinders: 490
total sectors: 125440
rpm: 3600
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0           # microseconds
track-to-track seek: 0  # microseconds
drivedata: 0 

5 partitions:
#        size    offset     fstype [fsize bsize cpg/sgs]
 a:     62704        32     4.2BSD      0     0     0  # (Cyl.      0*-    245*)
 c:     62704        32     unused      0     0        # (Cyl.      0*-    245*)
 d:    125440         0     unused      0     0        # (Cyl.      0 -    489)
 e:     62704     62736     4.2BSD    512  4096 15680  # (Cyl.    245*-    489)
# 

This used to work.  Any ideas what could have changed?
