Hi, I meet a problem with the new serial driver "uart" used in FreeBSD 8.0-Beta and Qemu. Hi all, Under Qemu, my "serial-console-only" FreeBSD 7.2 image (sio drivers) works great, but my "serial-console-only" FreeBSD 8.0-Beta4 image (uart drivers) doesn't works. I try to replace Qemu 0.10.6 with an "up-to-date" qemu-devel using this patch: http://people.freebsd.org/~nox/qemu/qemu-devel-20090829.patch But I've still the same problem (I start qemu with no-graphic). The startup log under FreeBSD 8.0-Beta4 stop here: (...) atkbd0: [GIANT-LOCKED] atkbd0: [ITHREAD] uart0: <Non-standard ns8250 class UART with FIFOs> port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0 uart0: [FILTER] uart0: console (9600,n,8,1) cpu0: <ACPI CPU> on acpi0 sc0: <System console> at flags 0x100 on isa0 sc0: VGA <16 virtual consoles, flags=0x100> vga0: <Generic ISA VGA> at port 0x3c0-0x3df iomem 0xa0000-0xbffff on isa0 Timecounter "TSC" frequency 1995170970 Hz quality 800 Timecounters tick every 1.000 msec IPsec: Initialized Security Association Processing. ad0: 476MB <QEMU HARDDISK 0.10.6> at ata0-master WDMA2 GEOM: ad0s1: geometry does not match label (255h,63s != 16h,63s). Trying to mount root from ufs:/dev/ufs/BSDRP1 cp: I've found this old message that report the same problem, but no solution here: http://lists.freebsd.org/pipermail/freebsd-current/2009-February/003222.html Anyone have an idea about this problem ? Is a FreeBSD bug or a Qemu bug ? What information can I give to you for troubleshoot this problem ? Thanks, Olivier
