Subject: NE2000 card sometims has memory but usually not ?

Running 2.2.5-RELEASE on a 486dx2-66, NE2000 clone (SimpleNet SN2000CT)
as network board.

I usually have

 Jan 11 09:57:28 dodo /kernel: ed0 at 0x300-0x31f irq 10 on isa
 Jan 11 09:57:28 dodo /kernel: ed0: address 00:40:05:1c:24:e0, type NE2000
 (16 bit)

in my log file, but today (and once , ~2 weeks ago) my card developed
a case of "memory gain", although flaky:

 Jan 12 19:05:54 dodo /kernel: ed0: failed to clear shared memory at d8000 -
 check configuration
 Jan 12 19:05:54 dodo /kernel: ed0 at 0x300-0x31f irq 10 msize 8192 on isa
 Jan 12 19:05:54 dodo /kernel: ed0: address 00:40:05:1c:24:e0, type NE2000
 (16 bit) 

How come the driver sometimes thinks there's memory, but usually doesn't ?

The doc mentions 16 Kbytes of Buffer RAM size, but it is unclear whether
that is internal to the card hardware or not.

Could there be a problem with the card, the driver, the config of
either, ...?
