My mobo is Gigabyte GA-BX2000 http://www.gigabyte.com.tw/products/bx2000.htm The CPU is a Celeron 300A, no overclocking during kernel panic test.

Well, via several kernel panic tests, I hope I've found out the key problem. I usually setup dummynet to limit my upstream bandwidth, especially ssh out, ftp out, cvsup out. This could explain why ssh doesn't cause panic while I do ssh localhost. And why it panics even I didn't do anything. (There's a crontab cvsup, and I limited cvsup upstream bandwidth by dummynet) And after I commented out all ipfw pipe and pipe config lines in my firewall script file, no more panics. Though I don't know how to fix it, I'll try to provide more information for real kernel hackers to fix :-) -- CirX - This site doesnt' exist. 9c k9o h9 s1bg s1f=, 7v .y xqx a sj m8r ffg1 vg5 a6 asox tmul h38 =. ant sj m8r ob =? 1fj mwby a1 tao vg5 =. soq df v ' .a.
