On a 5.4-pre system as of the last few days, If I mount a spun down hard disk (one I am using only for backup): # mount /backup/usr I get ad1: TIMEOUT _ READ DMA retrying (2 retries left) LBA=7340273 ad0: WARNING - removed from configuration ad1: WARNING - removed from configuration at0-slave: FAILURE - READ DMA Timeout mount:/dev/ad1s1g : Input/Output error ata0-slave: timeout state=0 unexpected initiate_write_filepage: already started initiate_write_filepage: already started (repeat until reset is pushed) Nothing works because all of the disks are unmounted. Can't even shut down. This worked great in 4.10, and also 5.3 (where the initial mount generated an error, but I could do the mount again after the disk spun up). Anybody else get the same thing? I'll open a bug report if so... -- Mike Harding <mvh@ix.netcom.com>
