Hello list (again). I'm sorry for the noize last night. I was way to sleepy ;) Now I had this proplem with a non-sleepable lock in if_xl.c (As explained in the previous post. Now, I did not provide alot of info in my last mail so here goes: FreeBSD caulfield.bitcode.eu.org 6.0-BETA2 FreeBSD 6.0-BETA2 #0: Sun Aug 21 22:21:18 UTC 2005 [EMAIL PROTECTED]:/usr/obj/usr/src.inuse/sys/caulfield i386 This is built from sources from around noon on Sunday. This proplem exist in -HEAD since there have been no changes in if_xl.c Now this morning I made myself a null-modem cable and went on to see what was scrolling by so fast because of this "bug". Attached is a log from the serial connection when I reboot the machine. This proplem "went away (TM)" also with my diff. Now I have been doing some further testing on the NIC and everything seems to be OK. PS: I though about CC'ing this to current also but... Am I going through the wrong channels here ? -- Thordur I. <[EMAIL PROTECTED]> Humppa!
