Analog joystick fails on 2.4.10

[Pascal Schmidt]

I have problems with the analog joystick support in 2.4.10. My gameport is
on an es1371 soundcard. I load the soundcard driver with

modprobe es1371 joystick=0x200

This works and results in:

es1371: found chip, vendor id 0x1274 device id 0x1371 revision 0x08
es1371: found es1371 rev 8 at io 0xdc00 irq 9
es1371: features: joystick 0x200
ac97_codec: AC97 Audio codec, id: 0x4352:0x5913 (Cirrus Logic CS4297A rev
A)

Then I do "modprobe analog". On 2.4.9-ac10, this results in:

input0: Analog 2-axis 4-button joystick at gameport0.0 [TSC timer, 450 MHz
clock, 928 ns res]

The joystick works after that. On 2.4.10, instead I get:

input0: Analog 2-axis 4-button joystick at gameport0.0 [TSC timer, -1187
kHz clock, -197135 ns res]

The values are of course bogus, and the joystick does not work.

"rmmod analog ; modprobe analog" gives a segmentation fault with this
syslog output:

This looks like modprobe's fault, ksymoops says:

Another try at "modprobe analog" after that returns without segfault, but
the analog module stays in "initalizing" forever, at least that's what
lsmod tells me.
