I suppose one starting point is make sure a pure-vanilla 3.6.10 kernel boots. This is what I would try: Do a lspci -k from whatever Linux you can boot, sysrescue CD or stick comes to mind here. That should list the drivers you need for hardware. Then mount partitions so you can get to /usr/src/kernel here and cat the config file and make sure the results from lspci are built INTO the kernel, not modules but built INTO the kernel. You could even do: 'cat .config | grep -i driver name from lspci -k here' Repeat that for each driver. Remember, arrow up keys for that one. Saves you some typing. lol If you have those built in, the only thing to check then is that the file system for / is also built INTO the kernel. That has always got me to at least a console login. Some other hardware may not work but you can boot and fix from inside the OS instead of booting DVD, USB stick or whatever and having to mount and such. That is such a pain to do. Maybe that will help. At least get you to a console. That alone makes fixing something else easier. Dale :-) :-) -- I am only responsible for what I said ...

Is it possible that you have two SATA drivers enabled and the two conflict each other? I read, I think on this list, where someone had to disable one driver for the correct driver to work. You may want to go here: http://kmuto.jp/debian/hcl/ Get the driver list from that and try it. On that site, you can use lspci or look up by model brand on the left. This is weird. If I think of anything else, I'll post but I'm sort of stumped. My previous post always gets me to a console login if nothing else. Once you get that, you can work out the rest.

Felix, Personally, after years reading LKML, I have no problem with in-line text of _any_ length, especially on the initial post or when you are asked to respond with detailed info. While I understand Bruce's comment I don't think it represents a democratic picture of what this list has been comfortable with over the years. That said, what I do have a BIG problem with is people responding and not taking the time to edit the response down to a few lines that make it clear about what their point is. Many responses to 1000 line emails are 1001 lines - the responder adds a one-liner. That's a real waste. It's a trade off. It's less likely that some of us will go read pastebin stuff, and if we want to respond technically then that's leaving us to copy/paste responses which I'm personally less likely to do. Anyway, you pays your money, you takes your chance... ;-) Cheers, Mark

Have you heard of attachments? pastebins? Felix, Personally, after years reading LKML, I have no problem with in-line text of _any_ length, especially on the initial post or when you are asked to respond with detailed info. While I understand Bruce's comment I don't think it represents a democratic picture of what this list has been comfortable with over the years. Agreed. That said, what I do have a BIG problem with is people responding and not taking the time to edit the response down to a few lines that make it clear about what their point is. Many responses to 1000 line emails are 1001 lines - the responder adds a one-liner. That's a real waste. Guilty. To be fair, I try to properly snip and edit when I can, but if I'm responding from my phone (more often than not, of late), getting that kind of editing work in is very difficult. -- :wq
[gentoo-user] 3.7.1 SATA errors
A few weeks ago I had a scare when a reboot paniced the kernel with a complaint that it could not find the root device (/dev/sde), and further reboots couldn't even see the USB keyboard. Leavng the system powered off overnight fixed the problem and the system has been working fine ever since. I have since had some time to explore this and find it related to the kernel; 3.6.10 works fine, while 3.7.1 fails. If I reset during the 3.7.1 boot while it is spewing its error messages, but before the kernel ultimately panics, I can reboot with 3.6.10, but if 3.7.1 goes all the way to the panic, I have to power off and wait a few minutes before a 3.6.10 reboot is succesful. This is repeatable, but I haven't bothered to see how long the system must be off; a few minutes is enough. This is a ~amd64 system, dual Opterons, Tyan S2882, Thunder K8S Pro. The dmesg times here start around 30 seconds because it spends 15 seconds on each of two SCSI hosts probing for nonexistent drives. udev etc are all frozen pre-systemd nonsense. Disks are two SSDs, two 4T drives, two 300G drives, and one 320G IDE/PATA drive; the main board is so old that there are only three boot options: IDE, DVD, network. There are two error messages during the 3.7.1 boot, repeated for all SATA drives: ata5.00: qc timeout (cmd 0x2f) ata5.00: failed to set xfermode (err_mask=0x40) Google does not enlighten me. One suggestion was change the SATA cable, but this is definitely a change from 3.6.10 to 3.7.1. So here are some details ... You can see everything at https://www.dropbox.com/sh/o8j80rps3agvvcf/FBjJLcykRS I am willing to try reasonable config changes for a new reboot attempt, but it is my main home server, not an experimental toy :-) dmesg differences I took some pictures during the boot process and transcribed the results. The 3.6.10 dmesg matches, but of course I can't get a 3.7.1 dmesg. Both 3.6.10 and 3.7.1 appear to be the same up to this point: ata13.00: ATA-8: WDC WD3200AAJB-00J3A0, 01.03E01, max UDMA/133 ata13.00: 625142448 sectors, multi 16: LBA48 ata13.00: configured for UDMA/133 ata1: SATA link down (SStatus 0 SControl 300) ata9: SATA link up 1.5 Gbps (SStatus 113 SControl 310) ata9.00: ATA-9: M4-CT512M4SD2, 000F, max UDMA/100 ata9.00: 1000215216 sectors, multi 16: LBA48 NCQ (depth 0/32) ata9.00: configured for UDMA/100 ata2: SATA link down (SStatus 0 SControl 300) ata3: SATA link down (SStatus 0 SControl 300) ata4: SATA link down (SStatus 0 SControl 300) ata5: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata5.00: ATA-7: Maxtor 6B300S0, BANC17M0, max UDMA/133 ata5.00: 586114704 sectors, multi 0: LBA48 NCQ (not used) Around here 3.6.10 begins scrolling so fast that I could not get any pictures, so this is from the 3.6.10 dmesg, where it diverges from 3.7.1: ata5.00: configured for UDMA/133 scsi 6:0:0:0: Direct-Access ATA Maxtor 6B300S0 BANC PQ: 0 ANSI: 5 sd 6:0:0:0: [sda] 586114704 512-byte logical blocks: (300 GB/279 GiB) sd 6:0:0:0: [sda] Write Protect is off sd 6:0:0:0: [sda] Mode Sense: 00 3a 00 00 sd 6:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sda: sd 6:0:0:0: [sda] Attached SCSI disk ata6: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata6.00: ATA-7: Maxtor 6B300S0, BANC17M0, max UDMA/133 ata6.00: 586114704 sectors, multi 0: LBA48 NCQ (not used) ata6.00: configured for UDMA/133 scsi 7:0:0:0: Direct-Access ATA Maxtor 6B300S0 BANC PQ: 0 ANSI: 5 sd 7:0:0:0: [sdb] 586114704 512-byte logical blocks: (300 GB/279 GiB) sd 7:0:0:0: [sdb] Write Protect is off sd 7:0:0:0: [sdb] Mode Sense: 00 3a 00 00 sd 7:0:0:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sdb: unknown partition table sd 7:0:0:0: [sdb] Attached SCSI disk and on and on until it boots.

But 3.7.1 pokes along slowly enough while generating its errors that I did get some pictures to transcribe, and this is where it diverges from 3.6.10. ata5.00: qc timeout (cmd 0x2f) ata5.00: failed to set xfermode (err_mask=0x40) ata5: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata5.00: qc timeout (cmd 0x2f) ata5.00: failed to set xfermode (err_mask=0x40) ata5: limiting SATA link speed to 1.5 Gbps ata5.00: limiting speed to UDMA/133:PIO3 ata5: SATA link up 1.5 Gbps (SStatus 113 SControl 310) ata5.00: qc timeout (cmd 0x2f) ata5.00: failed to set xfermode (err_mask=0x40) ata5.00: disabled ata5: hard resetting link ata5: SATA link up 1.5 Gbps (SStatus 113 SControl 310) ata5: EH complete ... for all ATA drives until it eventually panics because the root device, /dev/sde, is not found. 3.6.10 --- 3.7.1 conf changes I rebuilt the 3.7.1 kernel and logged all
