Can I use DDB within splhigh()/splx() block?

Dear, I ran my system with modified 4.1R kernel, and I hit a problem. System is hanged, and I cannot even use ddb to break on the console. Is that possible kernel is trapped in splhigh()/splx() block? Thanks, -- -- Rex Luo Tel : 886-2-25521814 Ext. 824 Fax : 886-2-25521824 e-mail

unpaired splbio() and splx() in vfs_unmountall()

at the same time. I use spl0() to solve the prolbem, but I think it's not the right way to do that. Can anyone provide some clues or suggestions. Thanks -- Rex Luo Tel : 886-2-25521814 Ext. 824 Fax : 886-2-25521824 e-mail : [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED
