I have a Fujitsu P-series notebook with integraded Prism wireless lan and an Ali USB chipset. I've been having issues with both of these, with the error messages containing a common error number, leading me to believe that they might be related, which is why I'm sending it to both lists, as well as Linux-kernel.
Kernel version is 2.4.19.
I'll start off with the wlan issues. Every so often (as little as 5 minutes after booting) my wlan card with stop working. When I try to run iwconfig to see what's going on, it can't detect the card anymore. Looking at the kernel logs, I'm getting the following error message: eth1: Error -110 writing Tx descriptor to BAP This happens before it stops working, but with much greater frequency right before it stops.
The USB problem is less annoying, but still a problem. Sometimes when I hook up a USB device, it gives an error such as "Error -110, device not accepting address." If I unplug it and plug it back in, I can get it to work.
I've tried passing the noapic option to the kernel - before this, I couldn't get USB working at all, but it didn't help with the other issues. I've also tried compiling a kernel without USB support, but that didn't help either. Any ideas on what's going on? Enclosed below are some /proc files that might come in handy. Thanks in advance.
