ERROR::handle_hc_chhltd_intr_dma:2592: handle_hc_chhltd_intr_dma

[CaptainRoot]

Hi,

my Raspberry Pi frezzes when using cgminer after a few minutes. Without using cgminer it runs stabel for weeks. In order to get the Pi working agan i have to disconnect an reconnect power.

Hi.

Some more debug info would be nice.

Please post the full output of sudo lsusb -v, and dmesg from boot until your breakage is experienced.

Also, cgminer appears to be for ASICs (?) - how are you running it on an ARMv6?

[CaptainRoot]

cgminer ist for mining with USB Asic Block Erupter.
The USB sticks are conneted to 3 DLink DUB-H7 an one 4PortUSB hub, each ist powered.
cgminer is compiled from source

comment was too long: >>> http://pastebin.com/MJiTqvQs

I count no less than 17 usb-serial devices attached to 5 x 4-port hubs. I'm amazed that this even works.

Can you post a lsusb -t as well?

[CaptainRoot]

the 17 usb-serial devices are USB ASIC Miner. Meanwhile thi setup runs without any problems on my NSLU2 with Linux hostname 3.2.0-4-ixp4xx #1 Debian 3.2.46-1 armv5tel GNU/Linux;
A other NSLU2 runs 90 usb-serial devices via 158 DLINK DUB-H7....

Your NSLU2 uses a PCI-attached EHCI USB host. This is the same hardware you get on a PC. The Raspberry Pi has an OTG host which has significant hardware differences. Chief of these is that there can be only 8 active USB transactions at a single time - we cannot handle any more than these. Accessing 17 devices at once is likely to run out of resources.

When you say the Pi freezes - how are you communicating with it? If USB dropped out then ethernet will drop out as well and SSH will fail. It could be that the Pi is perfectly fine, but has stopped talking to USB devices.

The number of hubs you are using is a problem:

• some of them have single TTs and you are plugging multiple USB1.1 devices into them. Multi-TT hubs are recommended.
• You are probably nesting hubs too deep. The hardware currently supports a max depth of 3 hubs for USB2.0 devices and 4 with a USB1.1 device attached to the end - but this is with USB2.0 devices that are fully compliant. If the devices are not strictly compliant, particularly with signal strength or packet SYNC size, then you will run into problems with daisy-chained hubs.

A better approach would be to buy 7-port hubs that actually have 7-port hub chips inside. That d-link hub contains 2x4-port hubs daisy chained together internally. In the meantime - flatten the tree as much as possible. Plug daisy-chained hubs only into the first 3 ports of the hubs to reduce the depth.

[CaptainRoot]

Thanks for your fast replay. I don't know that the NIC ist conected via "USB" too. I setup a serial terminal and run it again... now at the and there are more informations. I know thats it is crazy to drive so many USB-devices ;).
I orderd som Multi-TT Hubs for testing...

aha. So it is genuinely crashing.

Why are there so many disconnect messages at 105 seconds? Are you physically unplugging the devices?

The crash experienced is most likely due to memory corruption. The dwc_otg USB driver has been fairly well profiled in this regard - it's more probable that your serial port driver (cp210x) is doing something bad.

Can you add slub_debug=FPUZ to /boot/cmdline.txt and retry? This should at least see if there is a dangling pointer/use-after-free in cp210x. It will be much slower to boot though.

[CaptainRoot]

i only start the software cgminer.

With the option slub_debug=FPUZ nothing happend so far the system runs without any problems

[P33M]

Is there anything in dmesg? (usually SLUB will be very noisy if something goes wrong that it fixes) Can you pastebin the contents of dmesg?

[CaptainRoot]

There is still nothing special, i think.

Odd. Reboots like that are most often power-related.

Out of interest, are you able to successfully use all 17 mining devices simultaneously?

[CaptainRoot]

Yes, that ist no problem. All 17 miner are running, until the pi reboots :)

The Pi is powered by a Samsung Galaxy Charger about 1,2A, all hubs are powered, too
DLink 3A each
Main 2,5A
