For a while now I have been tracking down problem with ata that causes ad0 to be lost when I resume my laptop. I upgraded to 6.0-CURRENT yesterday and the new vesa console stuff apparently changed the timings just enough to allow the reinit of ata0 to successfully detect the disk. A full verbose boot can be seen here: http://borderworlds.dk/~xi/dmesg.txt When I am on vt0 suspend/resume works and I get the following: wakeup from sleeping state (slept 00:00:13) ata0: reiniting channel .. ata0: reset tp1 mask=03 ostat0=50 ostat1=00 ata0: stat0=0x50 err=0x01 lsb=0x00 msb=0x00 ata0: stat1=0x00 err=0x01 lsb=0x00 msb=0x00 ata0: reset tp2 stat0=50 stat1=00 devices=0x1<ATA_MASTER> ad0: setting PIO4 on Intel ICH4 chip ad0: setting UDMA100 on Intel ICH4 chip ata0: reinit done .. ata1: reiniting channel .. ata1: reset tp1 mask=00 ostat0=ff ostat1=ff ata1: reinit done .. However if I am in X the vesa console doesn't seem to slow down the reinit enough and I get this instead: wakeup from sleeping state (slept 00:00:16) ata0: reiniting channel .. ata0: reset tp1 mask=03 ostat0=80 ostat1=80 ata0: stat0=0x80 err=0x80 lsb=0x80 msb=0x80 ata0: stat0=0x80 err=0x80 lsb=0x80 msb=0x80 ata0: stat0=0x80 err=0x80 lsb=0x80 msb=0x80 ata0: stat0=0x50 err=0x00 lsb=0xfe msb=0x3f ata0: stat1=0x00 err=0x00 lsb=0xfe msb=0x3f ata0: reset tp2 stat0=50 stat1=00 devices=0x0 subdisk0: detached ad0: detached ata0: reinit done .. ata1: reiniting channel .. ata1: reset tp1 mask=00 ostat0=ff ostat1=ff ata1: reinit done .. ... and the system is not very useful after that. I hope this is enough to find a solution to the problem. If not please let me know what I can do further to help. -- Christian Laursen
