ndis0 bad behaviour

Hello,

upgraded today, FreeBSD 5.2-CURRENT #0: Thu Jul  1 15:41:58.
Recompiled ndis as always (actually, I think I had this problem for a
very long time, I have checked out version of ndis from 29 of March,
which always works fine ;), and got very nice backtrace, then I tried to
type something, input doesn't work, but wireless indicator flashed as
download was going on. After trying Ctrl+C to interrupt ftp client,
nothing happened. After Ctrl+Alt+Del there was some disk activity
(screen was freezed), and then my Thinkpad T40 started beeping (one long
beep ;), and only power button saved my ears ;)

Backtrace follows (thnx to my digital camera ;):
ndis0: watchdog timeout' at 22520920 (3%) 124.1K/s eta:77m <- lftp ;)
Sleeping on "ndisrst" with the following non-sleepable locks held:

--- trap 0x1, eip=0, esp = 0xcbb76d7c, ebp = 0 ---
ndis0: link down
ndis0: link up

of course, I could do ctrl+alt+esc and maybe see something, but since I
don't know what to look for, I didn't do that.
This is almost reproduceable (when downloading something big from ftp ;)

if there's anything I can do, please let me know (according this hang ;)

the card is Intel(R) PRO/Wireless LAN 2100 3B Mini PCI Adapter,
DriverVer   = 04/26/2004,1.2.2.9 (from w70n51.INF)
