Bug#490753: /boot/vmlinuz-2.6.18-6-686: kernel BUG at drivers/md/bitmap.c:1166!
Package: linux-image-2.6.18-6-686
Version: 2.6.18.dfsg.1-18etch6
Severity: critical
File: /boot/vmlinuz-2.6.18-6-686
Justification: breaks the whole system
I thought enabling an internal bitmap with mdadm might be a good idea, until I
started getting kernel panics. This happened twice during heavy write I/O to
a raid1 md device, on top of which is a crypt dm layer and a reiserfs file
system.
I've since removed the bitmap, but if you need me to re-add it and convey any
subsequent details from /proc/mdstat or whatever, let me know.
