trouble version 11 and 12 with lenovo T61

[PETER Verweij]

On a Thinkpad T61 the latest 2 versions give a trap when I insert a usb-dvb-t stick. A normal usb memorystick gives no problem. Version 7 works flawlessly. If you want the trapscreen or other information, please let me know

In general, yes, post trap screen. Also, always mention if it is UHCI (USBUHCD.SYS), OHCI (USBOHCD.SYS) or EHCI (USBEHCD.SYS). If it is about trap in USBEHCD.SYS:

Trap 000d in USDEHCD (V12)

no dumping set up

I set the system to boot and left it and came back to this state so I dont know what it was doing to get there. System usually works

when it has trapped before it has been well after the boot sequence

kernel 104a SMP ACPI /SMP /APIC trap info 000d

EAX b6643500 EBX ffff0000 ECX 07400024 EDX fd00b664 CS:EIP 06a8:000049a0 SS:ESP 1530:00004dce SSACC 1097 SSLIM 00003fff DS 06a0 ES 0000

error at ##0168:fff0f667 - 000f:e667

this has already been fixed and will be in the next build.

It is also in usbehcd, trap00d, but another location, picture added (made with phone)

Yes I found the error shonw in the trapscreen jpg. In fact, I found it by coincidence while I was reviewing the code. Again, the fix will be in the next build.

The first trap occurs on the preparation to remove the device,the trap shown in the jpg occurs when I device's data transmission "resources" are freed. It would be interesting to know how you triggered the error which would possibly allow me to reproduce it: 1.) did you have a USB device attached on boot ? 2.) did you unplug a USB device ? Did you unplug it without detaching the filesystem first (in case of memory stick) ? 3.) What device was it ? It should be USB 2.0 compliant, correct ?

Hi,

First thank you for the reply and work on usb! With the newly released version it works again. To answer your questions:

• usb devices is connected after the wps is started, then I got the trap statement, nothing fancy. If you want I can try to reproduce it with the old version.

From the usb resource manager the information of the usb device: <<< Device Description >>>
