According to the dmesg upon reboot, however, it is: panic: ata_dmasetup: transfer active on this device! syncing disks... 25 3 3 3 3 3 3 3 6 2 2 2 2 2 2 2 4 done Uptime: 6d23h8m36s >How-To-Repeat: We don't know exactly, what triggers it. Sometimes it is in the middle of the user doing something, sometimes it happens at night (during the daily runs?) Sometimes they notice, but the speakers suddenly going silent. But it happens once or twice per week and is... There are two disks in the system (I wish, the panic message did not use any pronouns!). The swap is on both of them: Device 1K-blocks Used Avail Capacity Type /dev/rad0b 262016 71476 190540 27% Interleaved /dev/rad2b 1048448 71260 977188 7% Interleaved Total 1310464 142736 1167728 11% The full dmesg.boot (beginning with the panic message) can be found at: http://virtual-estates.com/~mi/symbion.dmesg.boot >Fix: May be, forcing the ATA mode for the newer disk from UDMA100 down will be a work-around? >Release-Note: >Audit-Trail: >Unformatted:
