Watchdogtimer/transfer issue

[wdriever]

Dear Robin,

I have created multiple lspci and lsusb output textfiles. I can't upload them using this forum because of the following error:
Please correct the following errors before continuing:
The file upload failed. Please choose a valid file and try again. Error details: There was a problem moving the uploaded file to its destination.

I have tried a Latitude e7440 UEFI 64-bit laptop:
results:
00:19.0 Ethernet controller: Intel Corporation Ethernet Connection I218-LM (rev 04)
Subsystem: Dell Device 05cb
Flags: bus master, fast devsel, latency 0, IRQ 255
Memory at f7e00000 (32-bit, non-prefetchable) [size=128K]
Memory at f7e3c000 (32-bit, non-prefetchable) [size=4K]
I/O ports at f080 [size=32]
Capabilities: [c8] Power Management version 2
Capabilities: [d0] MSI: Enable- Count=1/1 Maskable- 64bit+
Capabilities: [e0] PCI Advanced Features

Transfer speed about: 2MB/s. Transfer is complete within 5 minutes, so this works. However if i leave the laptop in the iPXE shell for 5 minutes, the machine reboots.

Venue Pro 11 5130 (64-bit model) results:
These machines don't have NIC's. You can choose between a docking NIC or a USB dongle with a (supported by Dell) PXE chip.

These tablets are connected to a docking station but unable to use integrated NIC of the docking, therefore i cannot test this. This is not a iPXE issue.
Transfer speed: 10MB/s <- fast.
5 minute wait: machine reboots

Venue Pro 11 7130 (64-bit model) results:
Is used the same dongle as the 5130 model.
transfer speed: ~ 1MB/s
5 minute wait: machine reboots

All tested Dell hardware seem to reboot after 5 minutes. The used USB dongle is very fast in the 5130 but slow on the 7130.
The internal NIC of the e7440 laptop works but is slow.

The internal NIC's of the docking station is not visible in de lspci or lsusb output.
I hope this will give you the information you need.

Thank you for your help.
