[-- Attachment #1 --] Gang, :-) While working with Marcel on a bootable CD-ROM for IA64 issue, I've stumbled upon the following problem. I needed to increase the size of the EFI partition (which is an MS-DOS file system) to 64M, and that made two of my machines stuck solidly -- a lot of process are waiting on the "wdrain" event. The issue is not IA64 specific, both machines in question are i386. The following script makes my machines unhappy: EFISZ=131072 dd if=/dev/zero of=$BASE/$EFIPART count=$EFISZ md=`mdconfig -a -t vnode -f $BASE/$EFIPART` newfs_msdos -F 12 -S 512 -h 4 -o 0 -s $EFISZ -u 16 $md mount -t msdosfs /dev/$md /mnt dd if=/dev/zero of=/mnt/foo Changing to the -F 16 does not take any (good) effect. Anyone is interested in narrowing it down?
