Nice to hear it, because I have just switched my newly installed vmware
server (Debian Lenny, md raid1, vmware server) from CFQ to deadline
because CFQ is VERY slow, causes the entire system to hang for some
seconds every now and then, and it seems that it also crashed the whole
machine during intense I/O from the only virtual guest I have running (a
Win2008 with MS SQL server).
