[ltp] Kernel 2.4.20 and PCMCIA

Hello linux-thinkpad,

I'm running RH 8.0 on my 770ED. The system sits on a dock where the
floppy resides, along with a TDK CD-RW drive. On the dock's SCSI,
there is a Syquest SyJet with no disk in the drive. In the PCMCIA
slot, I have a 3Com/Megahertz 3CCFEM556 Ethernet/Modem card.

Running kernel 2.4.18-27.0, and several others before that, things
have been working pretty well. However, when I tried moving to the
first 2.4.20 kernel update that RH released, I had trouble. After
seeing some discussion here, it looked like it might have been caused
by PCMCIA difficulties. It looked more like that once I successfully
upgraded my A21p and three desktop systems (none of which use any
PCMCIA cards).

Now, I've tried upgrading to the latest 2.4.20-18.8, and my system is
still locking up at boot time. I am assuming that this is a "panic",
but since I can't remember seeing one on Linux before and since it
goes on for enough lines to scroll off the top of the screen, who
knows?

In /var/log/messages, the last few lines from my 2.4.20-18.8 boot
attempt are (without the date stamps):

pcmcia:  cardmgr.
cardmgr[598]: starting, version is 3.1.31
rc: Starting pcmcia:  succeeded
cardmgr[598]: config error, file 'config' line 2129: no function
bindings
cardmgr[598]: watching 4 sockets
cardmgr[598]: Card services release does not match

Note that the complaint about line 2129 also happens in the 2.4.18
boot. Note that the "Card services release does not match" complaint
also happens in the 2.4.18 boot.

In the 2.4.18 boot, what follows are lines from kernel/cs relating to
IO port probing, followed by the initialization of the Ethernet/Modem
card.

So, I guess I'm still suspicious of PCMCIA issues. Further evidence
pointing at PCMCIA is that when I pulled the card and re-booted, the
system came up fine (althouth, of course, not on the network).

Where do I go from here??? Thanks!

Ron.
