Vaio: yenta_socket fails to load (Answered)

[inti]

Hi. Anyone else have this problem? Running FC1 on a Sony Vaio laptop and pcmcia support seems to be broken.

pcmcia works with RH9 kernel 2.4.20-20.9, by the way. If I reboot with that kernel the yenta_socket module loads fine, even though I get the same IRQ error message.

Below is the output from insmod and the relevant info from dmesg.

Any ideas?

--------------------------
[inti@gobi] sudo insmod yenta_socket
Using /lib/modules/2.4.22-1.2115.nptl/kernel/drivers/pcmcia/yenta_socket.o
/lib/modules/2.4.22-1.2115.nptl/kernel/drivers/pcmcia/yenta_socket.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg

[inti@gobi] sudo dmesg

Looks like your PCI IRQ routing is broken. Try enabling ACPI kernel support by editing /boot/grub/grub.conf and adding the option "acpi=on" in the appropriate "kernel" line.

Thanks, kai_t. That did it. Enabling acpi was the trick.
