monti Posted October 19, 2015 Posted October 19, 2015 Hi again, I've a strange problem again. I've several Lime2 and tested them with USB-Sticks, works fine. Now I got a Fan-Tec case (USB 3.0 DB-ALU3-6G) containing a 4TB-SATA from a customer. As soon as I plug the disk into one of the USB-Plugs of a lime2, I got a kernel panic: Message from syslogd@localhost at Oct 19 17:49:20 ... kernel:[ 460.550693] Internal error: Oops: 17 [#1] PREEMPT SMP ARMMessage from syslogd@localhost at Oct 19 17:49:20 ... kernel:[ 461.304238] Process kworker/u:1 (pid: 55, stack limit = 0xee9702f0)Message from syslogd@localhost at Oct 19 17:49:20 ... kernel:[ 461.314387] Stack: (0xee971d78 to 0xee972000) .... Some facts: * USB-Sticks are no problem at all * No difference if formatted or not (2* FAT or 1 NTFS) * Kernel 3.105, 3.108, 3.109 crashes --> original images * Disabled any found *OTG and *USB-Gadgets Kernel parameter --> no success --> build with Igors script * Kernel 4.2.3-sunxi seems to work (but can't read, probably because its not a MBR), at least it dosn't crash* Lime2 with nand Unfortunatelly, 4.2.3 is not an option for me because NAND is not supported and I can't install a sd on every board. Found only this: https://github.com/raspberrypi/linux/issues/268, but couldn't follow completely. Any thoughs or hints? Or how can I get the nand to work on 4.2.3? Thanks for any help...
monti Posted October 20, 2015 Author Posted October 20, 2015 The original image from olimex (Linux a20-olimex 3.4.90+ #11 SMP PREEMPT Wed Aug 20 08:20:32 EEST 2014 armv7l GNU/Linux) crashes too... Tested also different boards. Do normal USB-Hard disks work generally? (May it's the chipset, maybe 4TB, maybe all USB-Disks?)
Igor Posted October 20, 2015 Posted October 20, 2015 The only issue regarding USB (that i remember now) is related to OTG port. Are you using it?
monti Posted October 20, 2015 Author Posted October 20, 2015 Hello Igor, no, I'm using only the two normal ports at the front side. Disabled also nearly anything in the kernel except EHCI, OHCI Allwinnner E/OHCI and USB Mass Storage... I will check tomorrow, if another harddisk will work in this fantec case.
Igor Posted October 20, 2015 Posted October 20, 2015 Check a script.bin and play with those settings too. Kernel might be just fine.
monti Posted October 21, 2015 Author Posted October 21, 2015 Checked: - Crash: script: disabled OTG-Port usbc0: crash - Don't work: script: set host_init_state=0: no usb at all - Works: used a 120GB HDD inside the fantec case So I think there is a 2TB barrier somewhere inside the kernel. But CONFIG_LBDAF=y seems to be set according to config-file.
Igor Posted October 21, 2015 Posted October 21, 2015 Have no idea why is this happening Better wait for NAND support on mainline kernel. I heard it's already done but not implemented yet. If problem happen there it won't be a problem to fix it since there are a lot of people working on it. On the other hand no one is taking care on legacy kernel any more ... except minor things. I am using 3T but on SATA and it works fine With Lime2 and legacy kernel.
