**** BEGIN LOGGING AT Tue Jun 22 02:59:56 2010 **** BEGIN LOGGING AT Tue Jun 22 10:15:29 2010 Jun 22 11:39:05 Marex: hello. Today I tryed to start my PalmTX with devel kernel, but kernel panics. starting ssh server it says that "Unable to handle kernel paging request at virtual address 40f00008. Could you advise how could I capture whole kernel output? Jun 22 11:40:20 do you have a serial cable ? Jun 22 11:41:25 no. I have only USB sync cable Jun 22 11:44:27 hm ... do you see the kernel panic on the screen ? Jun 22 11:44:45 btw. you use 2.6.35-rc3 or something, right ? Jun 22 11:45:50 yes, I see kernel panic, and I use 2.6.35-rc3. I could rewrite it by hand, but if where is easy way to capture output I'd prefer it :) Jun 22 11:46:06 no easy way ... pity Jun 22 11:46:22 trying to connect my USB cable I receive this output at my PC's /var/log/messages http://pastebin.com/wJYry0ED Jun 22 11:46:45 maybe a serial console could be connected somehow with my cable? Jun 22 11:46:52 btw after that Palm reboots Jun 22 11:47:46 after what ? Jun 22 11:48:10 after that output in log Jun 22 11:48:17 that's from palmos ? Jun 22 11:48:42 that's from my PC, I use gentoo linux Jun 22 11:49:01 but if PalmOS runs on the device ? Jun 22 11:49:05 or from linux ? Jun 22 11:49:15 maybe you didn't compile usb gadget support in ? Jun 22 11:52:01 PalmOS runs fine. if I connect cable to my palm, I receive that output I pasted into pastebin on my PC, then palm reboots. I today compiled into my kernel usb serial support, hoping to connect to serial console Jun 22 11:52:55 SiNGLer: try another USB port ... it might be some electrical discrepancy Jun 22 11:56:10 same problem. maybe I compiled some buggy feature into my kernel. I guess, I'll just rewrite that output for now Jun 22 11:56:50 SiNGLer: please do Jun 22 11:57:06 SiNGLer: the device restarts only if linux is running on it or both in palmos and linux ? Jun 22 11:57:52 only if PalmOS, on linux I didn't try it yet Jun 22 11:58:51 now I booted linux and got 2 traces, one trace is incomplete (I don't see a beginning), should I rewrite part I see, or just go to second one? Jun 22 12:00:14 the device is totalled, right ? Jun 22 12:00:24 like ... it doesn't show any signs of life anymore Jun 22 12:01:43 no, it is as usual kernel panic - no response. Last line: "Kernel panic - not syncing: Fatal exception in interrupt" Jun 22 12:04:34 hm Jun 22 12:24:03 partial trace: http://pastebin.com/z6cyECn9 will start filling in stack :) Jun 22 12:55:17 SiNGLer: try disabling the wifi driver (libertas) Jun 22 12:58:53 full trace: http://pastebin.com/NVUMMhQv Jun 22 12:59:44 wifi was disabled on PalmOs, should I recompile kernel without wifi or just remove firmware? Jun 22 13:01:28 removing the firmware should probably be fine Jun 22 13:01:57 SiNGLer: compile the kernel with kernel Debug->Stack unwinding Jun 22 13:04:24 "enable stack unwinding support" is marked Jun 22 13:14:28 deleting fw didn't help, I'll recompile kernel without wifi Jun 22 13:18:07 SiNGLer: hm ... go ahead Jun 22 13:22:20 kernel panicked without wifi Jun 22 13:33:00 SiNGLer: hm ... did you get any backtrace ? Jun 22 13:33:54 same as before just modules linked was empty, most of the stack was same Jun 22 13:34:59 SiNGLer: hm ... try removing the drivers ... one after another ... the first one I'd suspect is sound/touchscreen Jun 22 13:36:15 could it be some kernel option, which was automatically selected because my config was from older version? Jun 22 13:38:33 SiNGLer: I don't know ... I can send you some config I use with my hardware Jun 22 13:38:53 SiNGLer: pm me your mail Jun 22 13:39:26 pmed Jun 22 13:45:10 sent Jun 22 13:45:40 ok, thnx Jun 22 13:47:58 SiNGLer: it's not for palm platform and it may contain some debugging goo ... but that'll be helpful in tracing this one Jun 22 13:48:14 SiNGLer: just run menuconfig on it and select Palm TX instead of Voipac 270 Jun 22 13:49:38 ok, thnx once more :) I am compiling kernel now Jun 22 13:52:24 make[1]: *** No rule to make target `firmware/libertas/gspi8686.bin', needed by `firmware/libertas/gspi8686.bin.gen.o'. Stop. Jun 22 13:52:25 make[1]: *** Waiting for unfinished jobs....

Jun 22 13:53:33 SiNGLer: grep -v libertas .config > .config.new ; mv .config.new .config Jun 22 13:53:53 SiNGLer: you disable this somewhere in Drivers-> Select compiled-in firmware ... this shell command is faster Jun 22 13:55:10 ok Jun 22 14:03:34 kernel successfully loaded, but no touchscreen so I can't do anything with it. Thnx for it anyway, I'll start modifying it to support needed stuff :) Jun 22 14:05:58 I'm going home now, cya **** ENDING LOGGING AT Wed Jun 23 02:59:56 2010
