DragonFlyBSD

How was the stick written exactly?

I wrote the DragonFly image to the USB stick under Linux (openSUSE Tumbleweed) with the "dd" command:
$ dd if=DragonFly-x86_64-20160512-IMG.img of=/dev/sdb bs=1M
where the "/dev/sdb" is my USB stick, and no other extra options used except the "bs=1M".

(The FreeBSD image was written using the same "dd" command under the same Linux system, and it worked well.)

I will give the latest DragonFly snapshot a try tonight and report back. (I'm in China, UTC+8:00)

Hello,

I just tried the latest DragonFly snapshot (20160531) on my ThinkPad X200 but without luck, and the above issue remains the same. I checked the BIOS but found nothing special related to the USB.

On the other hand, I booted my new ThinkPad T450s with the same USB stick, and it worked and gave me the login.

The following information about my USB stick is extracted from the "dmesg.boot" with the working ThinkPad T450s:
------------------------------------------------------
da8: si_iosize_max:131072
da8 at umass-sim0 bus 0 target 0 lun 0
da8: <Netac OnlyDisk 1100> Removable Direct Access SCSI-4 device
da8: Serial Number AATN6P9DAV56PURL
da8: 40.000MB/s transfers
da8: 15474MB (31690752 512 byte sectors: 255H 63S/T 1972C)
da8: type 0xa5, start 63, end = 3887729, size 3887667 : OK
Mounting root from ufs:da8s1a
------------------------------------------------------

Hope it helps this issue.

Hello, I just tried to boot my ThinkPad X220 (another old laptop of mine) with the same prepared DragonFly USB stick. However, the same issue occurred on this ThinkPad X220 as that X200, and the boot process hung at the.

On the other hand, I checked the dmesg.boot from the working T450s, and there are many duplicated messages of "boundary check failed" (about 220 times) and "alignment check failed" (about 90 times). I do not known whether these messages are related to this issue.

• ThinkPad X200 (7457-4AC): Intel Core 2 Duo P8400, Intel GM45+ICH9M
• ThinkPad X220 (4290-LY3): Intel Core i5-2430M, Intel QM67; (no USB3.0 support)
• ThinkPad T450s (20BX): Intel Core i3-5200U, USB3.0

I think I found this bug is related to the "ehci" driver in DFly.

I took some efforts to make DFly run on my X220. Then I try to read the USB (2.0) stick from it, but it doesn't work with "ehci" driver loaded.

I tried following cases:
1. load "ehci" and "xhci"
2. load "ehci" only
3. load "xhci" only
4. neither "ehci" nor "xhci" loaded (i.e., only "ohci" which is built-in to the kernel)
The USB stick has "I/O error" for cases 1 and 2 (with "ehci"), but works for cases 3 and 4 (without "ehci")

The following is the dmesg for loading the "ehci" driver (I got these messages by first unloading and then loading the "ehci" driver):

I was also seeing this issue on my Thinkpad x201.
After flashing the alternativ coreboot BIOS all my USB sticks work perfectly.
Interestingly, FreeBSD and stock BIOS also worked ok.

How did you manage to boot dfly without the ehci driver? I'm facing this exact problem with my X220.

How did you manage to boot dfly without the ehci driver? I'm facing this exact problem with my X220.

In fact, it took me quite some effort to install DFly on my X200 (also X220), then I managed to find that this issue is in the "ehci" driver from the installed DFly system (I can kldload and kldunload the "ehci" and "xhci" drivers and check the logging messages).

By reading the loader(8) man page, there is a description on how to disable the auto loading of "ehci" (USB2.0) driver: go to the loader prompt, and input:
------------------------------------------------------------------
lunset ehci_load
set hint.ehci.0.disabled=1
------------------------------------------------------------------

WARNING: This issue of course exists in the installed DFly system, thus you can only work with the slow "ohci" (USB1.1) driver on X200/X220.

NOTE: I tried install FreeBSD and OpenBSD on my X200 (X220 should be similar), and both of them works well (w.r.t. the USB2.0 driver). However, DFly runs much faster compared to them, especially to OpenBSD.

Cheers,
Aly

(To be clear, the dmesg I attached doesn't include any attempts to use a USB device.)

I got the same error trying to install 6.0 on my Lenovo T430s.

Disabling ehci (per liweitianux's instructions above) didn't help: da8 just completely disappeared.

Fortunately, switching to a different USB port solved the problem. (The working one has an "SS" logo beside it.)

Thank you for the follow-up. Actually, the USB port with "SS" logo should be an USB 3.x port, which uses the `xhci` module and works fine in DragonFly.

I've tried to track this `ehci` issue quite some time ago, but failed to identify the cause ...
