Distribution: Debian stable/testing Hardware Environment: MSI 875P Neo PIV 2.8 GHz with HT, 1GB RAM, TI Firewire, NVIDIA GF 5200, Hauppauge TV Card 878, Yamaha sound card,Onboard sound disabled Software Environment: Problem Description: If both PATA channels and the SATA channel of the ICH5R are activated, Kernel hangs at booting with: ata1: DMA timeout, stat 0x21 ATA: abnormal status 0x7F on port 0x1F7 scsi0: ERROR on channel 0, id 0, lun , CDB: 0x28 00 00 00 00 00 00 00 08 00 current sda: sense=70 3 ASC=11 ASCQ= 4 Raw sense data: 0x70 0x00 0x03 0x00 0x00 0x00 0x00 0x06 0x00 0x00 0x00 0x00 0x11 0x04 end_request: I/O error, dev sda sector 0 ATA: abnormal status 0x7F on port 0x1F7 ATA: abnormal status 0x7F on port 0x1F7 ATA: abnormal status 0x7F on port 0x1F7 it does not hang in mode with one PATA channel and SATA activated. Only essential drivers for booting are compiled into the kernel. Running without libata only with the pata-driver and all channels works but system is consuming a lot of CPU time and system is some sort of unstable.(Finishing X freezes the system)
Do you have "enhanced" a.k.a. "native" a.k.a. "SATA" mode enabled in your BIOS? Avoid "legacy" or "combined" modes.
I tried both modes.
Does booting with "noapic" or "nomce" help? Can you provide full dmesg output for your machine, and "lspci -vvv" as root?
Created attachment 2399 [details] lspci -vvv output
Sorry, but the kernel parameters noapic and nomce didn't work. I can not provide dmesg output because I don't know how to do it without a running linux and access to a shell.
From mail exchange (closing bug now): > Have the problems indicated in > http://bugme.osdl.org/show_bug.cgi?id=2302 > > been solved by later kernels? Yes! Some weeks ago I tried it with kernel 2.6.9 and it works now.
