>Description:
mskc0: Uncorrectable PCI Express error. Error appears first time msk0 is initialized to an address, but only the first time. Error appears in startup messages if initialized via rc.conf or at the commandline. After anywhere between 3hours and a day msk0 stops functioning. I nfs my home directory so you can guess how I found out about it. Basically nfs gives an error that it can't access share "/whatever". As expected nfs hangs there giving errors until reboot. Just like when you are using wpa_supplicant and run the reset or shutdown sequence. NFS works fine on wireless although I get an initial buffer overrun error on my Netgear WG311T card (ath0). By the way, the myk binary driver version 8.14 from marvell crashes the system on startup.  
>How-To-Repeat:
ifconfig msk0 "netaddress and mask" up. Only happens the first time after reboot. A nfs connection should get the second problem to show up. I was using csup to update the ports tree the last time but it doesn't matter whether the connection is being used or not.
	
>Fix:
For the nfs failure on reset using the wpa_supplicant: sync first, then shutdown/reset.
