Hi,

I'm running kernels with pcmcia-cs-3.2.4 and linux-wlan-ng-0.2.1-pre11 (also tried 0.2). With 2.4.22-rc3 to final the system hangs if I insert my LevelOne WPC-0100 (Prism-II-base wlan), no output at all. Everything worked well up to and including 2.4.22-rc2.

Regards,
Christian

Out of curiosity, what happens when you remove the card? Does the system come back to normal or does it stay in the same state?

Hi.

Similar results here, except I can be more specific. I see the issue using pcmcia only. The package I'm using is the external-to-the-kernel-tree pcmcia-cs-3.2.3. Under 2.4.22, I get a complete freeze (no SysRq, no flashing cursor) when I insmod i82365.o. I tried recompiling the whole kernel & modules using gcc 2.96 and 3.2 to no avail. If I use the kernel tree's code, I can insmod okay, but my ltmodem_cs driver reports the modem as being busy all the time. The problem was fixed by reverting to 2.4.21 (I'd already deleted pre2, which was working). No configuration changes required - just a recompile.

Regards,

Nigel

Hi,

I already encountered similar problems.

Check if the PCMCIA slot is not on the same IRQ as ACPI in /proc/interrupts. You can also try to use a different PCMCIA slot, or boot with "acpi=off".

Cheers,
Willy

Now I just need to learn how to get it to assign a different IRQ.

Add "exclude irq 9" to /etc/pcmcia/config.opts
