	bootstrap loader problem by Don L. Belcher :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message New Dell 1737 laptop The following error occurs with versions 7.2 release and later this message is from 8 RC2. All versions tried with 7.1 release and earlier work fine, I tried 7.1, 7.2 and 6.4. I rebuilt 8 RC2 CD with "loader" from 7.1 release and the 8 RC2 comes up O.K. now. I have two questions: 1) is anybody familiar with this problem 2) is it ok to install 8 RC2 using the 7.1 "loader" BTX loader 1.00 BTX version is 1.02 Consoles: internal video/keyboard panic: free: guard1 fail @ 0xbb797074 from (diretory path to) common/console.c:94 --> Press a key (etc) _______________________________________________ freebsd-current@... mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscribe@..."

Can you try compiling a loader on 8 that doesn't include GPT support? (cd /sys/boot; make LOADER_NO_GPT_SUPPORT=yes) A loader from 7.1 should work ok on 8.0. -- John Baldwin _______________________________________________ freebsd-current@... mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscribe@..."

I installed to hard drive and the "loader" does not exhibit the problem. The problem only shows up when booting from CD ROM. The boot from CD ROM works OK using the "loader" built with make LOADER_NO_GPT_SUPPORT=yes > A loader from 7.1 should work ok on 8.0. > > _______________________________________________ freebsd-current@... mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscribe@..."

Hmmm, I know other people tested that change because I had to add bounce buffering to the CD drivers in the loader for buffers > 1MB. I could perhaps have a bug in the bounce buffering code that is trashing malloc's internal state if it does a buffer overrun of some sort. -- John Baldwin _______________________________________________ freebsd-current@... mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscribe@..."
