Hi Guys,
I am trying to bring pcmcia up on my mpc855 based board. I am using
kernel-2.4.18 and have pcmcia extensions.
I am making pcmcia as module, so I can insmod pcmcia_core and m8xx_pcmcia
and ds. When I insert the card and start cardmgr, this is what I get.
Starting PCMCIA services: cardmgr[79]: watching 2 sockets
done.
cardmgr[80]: starting, version is 3.2.5
cardmgr[80]: socket 1: 350 Series Wireless LAN Adapter
# insmod: insmod: char-major-4: no module by that name found
cardmgr[80]: executing: 'modprobe airo'
cardmgr[80]: + Using /lib/modules/2.4.18/kernel/drivers/net/wireless/airo.o
cardmgr[80]: executing: 'modprobe airo_cs '
cardmgr[80]: + Using
/lib/modules/2.4.18/kernel/drivers/net/wireless/airo_cs.o
m8xx_pcmcia: voltage_set slot=B, vcc=5, vpp=5
<7>m8xx_pcmcia: Service(1, 4, 0xc1e9180c)
m8xx_pcmcia: WRX voltage_set slot=B, vcc=5, vpp=5
<7>m8xx_pcmcia: Service(1, 8, 0xc1e91870)
Kernel panic: request_irq
<0>Rebooting in 180 seconds..
What am I missing here?? why is it trying to insmod char-major-4?? and why
does the kernel panic??

The kernel panics because in 2.4.18 a call to request_irq() would simply
panic. If you hit google, you can probably find a patch to airo.c to
make it use request_8xxirq() and 'work', or if you update to 2.4.21 (or
was it 2.4.20, I forget now), this is not an issue.
