I sent this originally to the pcmcia list, but haven't seen a response yet.
My laptop freezes as soon as I insert a Linksys WPC11 card which is an 802.11b wireless card. I don't think it's the driver since as far as I can tell, the drivers aren't included in the kernel (it's a prism 2). I first tried with a 2.6.1 kernel and then upgraded to 2.6.4 but it still acts the same. (I'm using Fedora Core Testing, updated to latest.)
The laptop is a Compaq Presario 2190, the cardbus is: 00:0a.0 CardBus bridge: O2 Micro, Inc. OZ6912 Cardbus Controller Subsystem: Hewlett-Packard Company: Unknown device 0024 Flags: bus master, stepping, slow devsel, latency 168, IRQ 11 Memory at 80000000 (32-bit, non-prefetchable) Bus: primary=00, secondary=02, subordinate=05, sec-latency=176 Memory window 0: 81000000-81100000 (prefetchable) Memory window 1: 10000000-103ff000 I/O window 0: 00003000-0000307f I/O window 1: 00004000-000040ff 16-bit legacy interface ports at 0001
dmesg shows: Yenta: CardBus bridge found at 0000:00:0a.0 [103c:0024] Yenta: ISA IRQ mask 0x0498, PCI irq 11 Socket status: 30000007 cs: IO port probe 0x0c00-0x0cff: clean. cs: IO port probe 0x0100-0x04ff: excluding 0x200-0x207 0x220-0x22f 0x330-0x337 0x378-0x37f 0x388-0x38f 0x3c0-0x3df 0x408-0x40f 0x480-0x48f 0x4d0-0x4d7 cs: IO port probe 0x0a00-0x0aff: clean.
I just noticed that it did get a message in /var/log/messages: Apr 1 09:48:57 localhost kernel: cs: memory probe xa0000000-0xa0ffffff: clean. Apr 1 09:48:57 localhost cardmgr[1001]: socket 0: Intersil PRISM2 11 Mbps Wireless Adapter
That's the last thing in the log before the next startup. If the card was already in when I booted it, then there was one more line in the log from the next booting step before it hung.
Further probing shows that the computer is still functioning as I can use sysrq functions. Using sysrq-p gives me a list that appears to scroll off the screen. From the top of the screen, the first few items are: alloc_netdev ether_setup orinoco_cs_hard_reset orinoco_cs_attach orinoco_cs_event bind_request kmem_cache_alloc bind_request ds_ioctl get_random_bytes arch_align_stack mmap_top mm_init
I have updated the laptop's bios to the latest version. Any other information that would be helpful?
