I've now been running with 2.6.21-rc2-git1 + Mikaels original "patch bundle" for 7 days without hangs! The machine has 2 Seagate 7200.7 disks and 2 Seagate 7200.10 (in 3.0Gps mode) with Promise Sata300TX4. The system does spit the following messages whenever there is load (no hickups user noticiable hickups however): Mar 4 03:51:13 alderan kernel: ata4.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0 Mar 4 03:51:13 alderan kernel: ata4.00: cmd 25/00:00:3f:0e:a8/00:04:09:00:00/e0 tag 0 cdb 0x0 data 524288 in Mar 4 03:51:13 alderan kernel: res 50/00:00:3e:12:a8/00:00:09:00:00/e0 Emask 0x1 (device error) Mar 4 03:51:13 alderan kernel: ata4.00: configured for UDMA/133 Mar 4 03:51:13 alderan kernel: ata4: EH complete Mar 4 03:51:13 alderan kernel: SCSI device sdd: 976773168 512-byte hdwr sectors (500108 MB) Mar 4 03:51:13 alderan kernel: sdd: Write Protect is off Mar 4 03:51:13 alderan kernel: SCSI device sdd: write cache: enabled, read cache: enabled, doesn't support DPO or FUA > > Then I applied just a single patch to 2.6.21-rc2: Mikael Petterssons > patch to force 1.5Gbps operation and tested again - this time no > problems at all! > > (BTW: both kernels are running with IO-APIC disabled). I have io-apic enabled, Asus A7V880 (Via KT880-chipset). In the past, when ever one of the disks failed, it _never_ was the first disk on the linux system (although I don't remember if it was connected to promise-cards first port as the ports are still numbered in some very pecualiar way under linux).
