Hi Juergen, there are two other bugs referred to in the report: 6397774 marrakesh often hangs in suspend-state 33 6455736 ata/dadk/cmdk should support DDI_SUSPEND/DDI_RESUME and the evaluation indicates that 6398361 was tentatively assumed to have been resolved along the way with 6455736. This is an excerpt from the comments: My guess is that this corruptions is due to a disk driver problem (also the likely cause of 6397774). If the driver doesn't properly suspend, or disk activity is attempted _after_ the driver is suspended, I believe that corruption can occur. > I'm asking because a "Western Digital WD1000BB" ATA HDD appears to have died > after the box was bfu'ed to current onnv-gate bits, which are containing > the changes for "6455736 ata/dadk/cmdk should support DDI_SUSPEND/DDI_RESUME" > as part of the "PSARC/2005/469 X86 Energy Star compliance" putback. > (The "Western Digital WD1000BB" ATA HDD has been frequently spinning down, > and the BIOS doesn't detect the HDD any more) > And a replacement HDD is making similar strange noises (HDD stops and > restarts) during S-x86 kernel boot time, which I've now traced to the > ATC_STANDBY_IM 0xe0 command in the ata_power() entry point. If you bfu to the night before Randy's putback does the issue go away? Can you bfu to the night before? James C.
