Question Panic on card insert on ppc g3, 3.1.11 / 2.2.x

I'm getting a kernel panic when I insert a pcmcia card on my PowerBook G3 (Lombard). Is this a known problem?

It happens with pcmcia-cs 3.1.11 and kernel 2.2.15pre7 from linuxcare.com.au, as well as with 3.1.1 and 2.2.14 (from which I upgraded). The panic looks basically the same with either a Lucent Wavelan 802.11HR card or an old Megahertz 14.4kbps modem.

I apologize for not including actual ksymoops output; I can't paste into this web browser. The panic is due to a NULL dereference in pcmcia_core, invoked by cardmgr through an ioctl. The bottom few routines vary but tend to include parse_cftable_entry(), validate_cis(), add_interval(), read_cis_cache(), get_{first,next}_tuple(), etc. I can post the read ksymoops output if necessary.

By playing around and running insmod, cardctl, etc. by hand, I did get pcmcia-cs to initialize the Wavelan card twice, once as an "anonymous memory device" and once as a "Melco WLI-PCM-L11", but inserting the card into the slot after loading the modules & starting cardmgr invariably causes a panic.
