On 29 Nov 2009, nix@xxxxxxxxxxxxx spake thusly: > One qemu-kvm-specific bug, definitely non-kernel-related, is this crash, > frequently encountered when hotadding more than one USB device (to an XP > guest, as it happens, but that doesn't look relevant here): I also see a crash when using -usbdevice on the command line. Symptoms are a very long pause instead of booting, and then (in an XP guest, immediately after the windows desktop appears; so I suspect the instant the guest tries to probe for USB devices): *** glibc detected *** /usr/bin/qemu: corrupted double-linked list: 0x0000000002908ce0 *** ======= Backtrace: ========= /lib/libc.so.6[0x7f87cc91a505] /lib/libc.so.6[0x7f87cc91d96d] /lib/libc.so.6(__libc_malloc+0x6e)[0x7f87cc91ef1e] /usr/bin/qemu[0x47037e] /usr/bin/qemu[0x423585] /usr/bin/qemu[0x42366f] /usr/bin/qemu[0x43e620] /usr/bin/qemu[0x4c73e8] /usr/bin/qemu[0x40a274] /usr/bin/qemu[0x421e6a] /usr/bin/qemu[0x40e7f5] /lib/libc.so.6(__libc_start_main+0xfd)[0x7f87cc8c8a7d] /usr/bin/qemu[0x407d29] ======= Memory map: ======== malloc() or overrun trouble. Fixed by c4c0e236beabb9de5ff472f77aeb811ec5484615, with the caveat that the 2048-byte buffer provided by this commit is nowhere near large enough: I have seen 4104 bytes coming back from an ipod nano 5 (thanks to the overrun detection also added by that commit). So I've boosted it to 8192 here, and it seems to work (albeit killingly slowly). -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
