Thanks.
Rene, can you send me copies of /proc/ide/hda/identify and /proc/ide/hdc/identify? I still would like to know why these drives don't accept flush cache commands (or it is a driver's bug?).

There is a problem with new 2.6 generic ->shutdown framework, it doesn't differentiate between reboot / halt and power_off. We may try to fix it or revert to 2.4 way of doing things if this is too big change for 2.6.
Thanks, Bartlomiej
