I tried to upgrade my laptop to 6.1, and the network boot disk failed.
It would throw a kernel oops on starting pcmcia and basically die.
Unfortunately, it's kind of hard to get useful information out of the
system when the installer's going.

(BTW, 6.0 worked fine, AND 6.2beta seems to work with pcmcia)

Anyway, I tried upgrading manually, and was able to reproduce it after
installing the 6.1 kernel / pcmcia tools.

Output is as follows:

[root@soro /root]# /etc/rc.d/init.d/pcmcia start

I can't really run a ksymoops on this easily, since the system is kind of
munged.  Here are the modules installed:

tulip_cb
cv_enabler
ds
i82365
pcmcia_core
loop
opl3
sb
uart401
sound
soundlow
soundcore

Interrupts:
 0 timer
 1 keyboard
 2 cascade
 5 soundblaster
 8 rtc
13 fpu
14 ide0

IO ports:
0000-001f : dma1
0020-003f : pic1
0040-005f : timer
0060-006f : keyboard
0070-007f : rtc
0080-008f : dma page reg

If you need more information, like a valid ksymoops spew, I'll be able
to extract something given some more effort.
