Subject: [PCMCIA] cardmgr (or something) crashes the kernel.
Date: Thu, 29 Jun 2000 15:07:05 +0900	[thread overview]
Message-ID: <001a01bfe190$40457fe0$1952df8d@SOYANG> (raw)


Hello.

After I've posted PCMCIA network card recommendation related message, I have optain one card from a friend.

It is named as "3Com Megahertz 10/100 LAN PC Card Model 3CCFE574BT".

I accomplished everything from ftp://ftp.absolval.com/pub/rpxlite/.

When I executed rc.pcmcia script this message follows and kernel is crashed.

/* message from console */

I've assigned M8XX_BUSFREQ in pcmcia-cs-3.1.10/modules/m8xx_pcmcia.c to 50 * 1000000, since my board is RPX Lite 850 SR 50Mhz

What's the main cause of problem?

The cardmgr?, The modules - pcmcia_core, m8xx_pcmcia, ds - ? or that The card itself is unsupported?

Please answer.

Thanks in advance.
