A PCRE internal error occured. This might be caused by a faulty plugin

June 29 6:45 PM: Current status: Up until now, I have completed most of the data structure definitions, skge_probe(), and skge_open(). I am obviously quite behind compared to my project plan, but that is not something I can easily resolve; However; It does look like I will have time still left over at the end of writing the skge driver for some other prospects in this task. Possibly tg3? So, after basicly 3 days off (except for a little work on saturday during and after my meeting) I'm ready to get going. It's 6:47 PM and I'm about to start on skge_transmit(). June 29 2:00 AM (really June 30): It's been a productive night; I discovered and fixed another memory issue with the allocation of Adapter; Once that was dealt with, I implemented skge_transmit and skge_poll. I'm not certian as I haven't setup wireshark yet, but I believe that I just saw my skge driver transmit it's first packet. I also pretty much overhaulled the DBGP commands so that anyone interested in writing a driver can literally just look at the output and understand all that is going on. <code> skge_probe - start | |-> Allocating 88 bytes of private space |-> Registering skge_operations with the core |-> Creating link to device |-> Allocated 68 bytes for the adapter at 0x18d74 |-> Zero out from 0x18d74 to 0x19f84 |-> Adapter Base set to 18d7c |-> ioaddr set to d800 |-> Using IRQ Number 10 |-> Assigned the Back and pdev pointers |-> Defining the length of the regiser locations |-> Mac Address of Port 1 : 00:21:91:91:10:6d |-> Beginning skge_initialize | |-> Triggering a software reset | |-> Waiting for one second . . .
