My normal workstation machine works just fine but my server wouldn't boot. I try to boot single-user mode but when it comes to asking about shell it just stops - actually it never display's that line. It works now because I saw the mail i'm qouting and enabled USB IRQ. It works fine with the 4.3 kernel (without an USB IRQ). But before I found that fix I enabled the kernel debuger and saw a very strange thing. When I brake to the debugger I can see the "missing" output - and I can see that the shell command-line is there. When I then exit from the debugger it again doesn't respond and when I when break to the debugger again i can see the command i typed while the computer didn't respond and commands i have type (ls osv.) have been executed... I can't see how this can be related to the USB IRQ thing, but when I enable that USB IRQ assigment in the BIOS everything works fine. I have no idea where to look for the bug, but if anyone would look at it i will gladly help. Should i file a PR for this? - -- /Simon -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (FreeBSD) Comment: For info see http://www.gnupg.org iD8DBQE7qll08kocFXgPTRwRAmu7AKClkoElvVJCstbHlkIpVhejGrKxkwCaAnn4 kh1eL4xYzw7mfQRThgTqtug= =ixwz -----END PGP SIGNATURE----- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
