This seems to happen only at boot, and not everytime (perhaps at 1/4 of all boot attempts, on average). If the machine actually manages to boot, then all seems well, and I haven't yet seen it when the system was running. Windows XP is also on the box and it doesn't seem to have any problems. I also didn't encounter any problems of that kind with earlier 5.4-STABLE snapshots. The machine is using the Intel ICH6 chipset, with disk and controller as following: atapci1: port 0xfea0-0xfeaf,0xfe30-0xfe33,0xfe20-0xfe27,0xfe10-0xfe13,0xfe00-0xfe07 irq 20 at device 31.2 on pci0 ad4: 152627MB [310101/16/63] at ata2-master SATA150 >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
