Hi, I am deploying 2.6.34.8-15 on many machines successfully. With about 10 HP Workstations I regularily get the following message in the kernel log: [ 1751.292702] ata1.00: exception Emask 0x10 SAct 0x0 SErr 0x4010000 action 0xe frozen [ 1751.292706] ata1.00: irq_stat 0x00400040, connection status changed [ 1751.292710] ata1: SError: { PHYRdyChg DevExch } [ 1751.292712] ata1.00: failed command: FLUSH CACHE EXT [ 1751.292719] ata1.00: cmd ea/00:00:00:00:00/00:00:00:00:00/a0 tag 0 [ 1751.292720] res 40/00:04:83:02:ee/00:00:02:00:00/40 Emask 0x10 (ATA bus error) [ 1751.292723] ata1.00: status: { DRDY } [ 1751.292728] ata1: hard resetting link [ 1756.044876] ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [ 1756.047118] ata1.00: configured for UDMA/100 [ 1756.047122] ata1.00: retrying FLUSH 0xea Emask 0x10 [ 1756.047250] ata1: EH complete I also experience severe data loss whenever such an error occurs. Typically I cannot issue "make config" in the kernel sources anymore on an affected system due to binary garbage in C-Sources. Any hints? Shall I open a bugzilla entry? BTW: I already pulled all BIOS options including an upgrade to the most recent and different energy saving options for SATA.
