[Linux-gpib-general] PCMCIA issue on kernel 5.4.0-54-generic (Linux Mint 19.3)

[Mitchell C. <mo....@gm...>]

Hi,

I am trying to build the linux-gpib kernel module with PCMCIA enabled for
Linux Mint 19.3 with kernel 5.4.0-54-generic, with a National Instruments
PCMCIA-GPIB card. When I try to modprobe the tnt4882 driver into the
kernel, I get:
$ sudo modprobe -fvv tnt4882
modprobe: INFO: ../libkmod/libkmod.c:364 kmod_set_log_fn() custom logging
function 0x55eae3517750 registered
insmod /lib/modules/5.4.0-54-generic/gpib/tnt4882/tnt4882.ko
modprobe: INFO: ../libkmod/libkmod-module.c:886 kmod_module_insert_module()
Failed to insert module
'/lib/modules/5.4.0-54-generic/gpib/tnt4882/tnt4882.ko': Exec format error
modprobe: ERROR: could not insert 'tnt4882': Exec format error
modprobe: INFO: ../libkmod/libkmod.c:331 kmod_unref() context
0x55eae482e420 released

with dmesg output:
$ dmesg | tail

[ 7116.877253] gpib: registered ni_pcmcia_accel interface
[ 7116.877256] kobject: can not set name properly!

I don't think this is an issue of compiling against an incomplete symbol
table, as the gpib_common and nec7210 drivers are in my kernel:
$ lsmod | grep nec7210
nec7210                24576  0
gpib_common            45056  1 nec7210

and so is the pcmcia driver:
$ lsmod | grep pcmcia
pcmcia                 65536  0
pcmcia_rsrc            24576  1 yenta_socket
pcmcia_core            28672  3 pcmcia,pcmcia_rsrc,yenta_socket

I have no issues inserting tnt4882 into the kernel if I build it without
PCMCIA enabled (i.e. make ENABLE_PCMCIA=0). Does anyone have any idea what
is going on? Thanks.
