Paolo Thanks , this is good to hear the I/O error in the guest EXT3 file system might have been just heavy usage then , only 256 MB of RAM and no swap partition ( it was badly configured , I know ) . There seemed to be some sort of timeouts both for git and the file system. I might try something else like ext4, more RAM and swap then see if the error persists. Once again thanks and on a personal note we have a Frugalware dev. and friend of mine named Paolo too.
[Qemu-devel] lsi_scsi: error: ORDERED queue not implemented
Hello I'm using : qemu-system-arm --version QEMU emulator version 1.0,1, Copyright (c) 2003-2008 Fabrice Bellard and I have a premade ARM image which I start with: qemu-system-arm -M versatilepb -m 256 -kernel vmlinuz-3.1-versatile-fw5 -hda initrd-arm.img -append root=/dev/sda ro quiet Every now and then I get this: lsi_scsi: error: ORDERED queue not implemented I'm not sure why this is, both host and guest run Frugalware Linux which is not very famous , kernel is at version 3.2 The file system for the guest is ext3, mounted from /dev/sda. The IO fails sometime in the guest system and it seems very slow in general. If you need any more information let me know. I can reproduce this every time I make IO intensive operations like git clone on a large repository.
