Hi,
My newly build kernel (2.6.30.4--grsec, under pv_grub-64) seems to fail - it's exactly the same .config as my previous kernel (2.6.27.10-grsec), which was working fine.
It fails with:
Code: Booting 'Debian GNU/Linux, kernel 2.6.30.4-grsec'
root (hd0)
Filesystem type is ext2fs, using whole disk
kernel /boot/vmlinuz-2.6.30.4-grsec root=ca00 ro
close blk: backend at /local/domain/0/backend/vbd/628/51712
close blk: backend at /local/domain/0/backend/vbd/628/51728
close blk: backend at /local/domain/0/backend/vbd/628/51744
Config: config-2.6.30.4-grsec4, config-2.6.27.10-grsec
Any ideas?
Thanks |

This one may be due to an issue we've been seeing recently. Can you roll back to 2.6.29 in your pv-grub setup for the time being? |

I've seen the same thing happen when the kernel is built with --fstack-protector
Once I disabled that in the kernel config, it booted flowlessly.
Not sure if this applies to GRSec though...
edit: just checked your config, it's off. ignore me ... :) |

Yes, I have already done so. Nice to see that you are always on top of things .... :-) |
