Public bug reported:

I'm trying to use a brand newly installed system (at an ISP), which has
a 3ware RAID card:

05:00.0 RAID bus controller: 3ware Inc 9650SE SATA-II RAID PCIe (rev 01)


after a brand new Ubuntu 10.04 64bit install, I'm simply using dselect to 
install the packages I want - and running a number of rsync instances in the 
meantime, to transfer data. on two different occasions, this resulted in dpkg 
crashing, so much that in fact I couldn't even kill it with kill -9. this is 
what I got in syslog:

interestingly, when I killed the rsync processes, dpkg somehow got
resurrected the second time.

this is all kind of disturbing, as it seems on a bit heavy disk I/O, the
raid subsystem becomes unstable - what could be the issue here?

here's some additonal info on the system:
