**** BEGIN LOGGING AT Wed May 23 03:00:03 2018 May 23 07:13:12 ant_work: OE had the issue before https://patchwork.openembedded.org/patch/125405/ May 23 07:13:39 I can confirm that mkfs.ext4 /dev/sdc1 -O^metadata_csum creates a bootable fs May 23 07:13:53 legacy grub can not deal with checksums too May 23 07:14:54 ah May 23 07:15:09 I think grub had a patch to ignore this, but I can not find it. It may help May 23 07:15:14 so I was using a patched recipe May 23 07:15:46 yes, the older e2fsprogs was patched May 23 07:15:53 in OE at least May 23 07:19:35 I tried the MS_VERBOSE but its obsolete and also misnamed, its actually for supressing kprint warnings ;/ May 23 07:19:42 http://man7.org/linux/man-pages/man2/mount.2.html May 23 07:19:59 so no luck there to get more info, but its the checksum feature for sure May 23 07:20:50 I think it would be sensible to advise user in the install guide disable it when creating a ext4 fs. Checksum creation possibly slows down things anyway on a Zaurus. May 23 07:24:39 argh laptop May 23 07:25:05 greguu, so you only see 'unknown option' or alike May 23 07:25:25 "invalid argument"+ May 23 07:25:31 right May 23 07:25:44 its the checksum feature May 23 07:26:13 debug must be enabled in kernel then May 23 07:29:06 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/fs/ext4/ioctl.c?h=v4.17-rc6#n688 May 23 07:31:29 this exist since 3.5 or so. I think the kernel is not at fault here May 23 07:32:00 I am just scrubbing rapidly, don't see any debug hook tough May 23 07:33:53 heh May 23 07:33:54 config EXT4_DEBUG May 23 07:45:25 https://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git/commit/misc/mke2fs.conf.in?id=d0b9e0a6aa7d6805338a43b4e372623352d8df09 May 23 08:06:04 greguu, I see a Pentium II is slowed down May 23 08:06:17 poor Z May 23 08:06:18 https://ext4.wiki.kernel.org/index.php/Ext4_Metadata_Checksums May 23 08:10:52 yes, thats why better not enable the feature. Move to F2FS instead or stay with ext3 for older devices May 23 08:11:38 f2fs has checksums too **** BEGIN LOGGING AT Wed May 23 08:27:17 2018 May 23 09:32:23 ant_work: you have the serial cable ? I think dmesg would show more details May 23 09:36:35 its clear the metadata checksum is causing the issue, however it should be fine if mounted readonly. May 23 09:37:02 kexecboot seems to attempt readonly mount. strange that it fails. May 23 10:47:11 need to build a kernel with debug (and printk) otherwise kexecboot is silent May 23 10:49:49 greguu, just to resume, every kexecboot kernel fails to detect/mount the new ext4 or only the old 3.x? May 23 13:17:51 Omegamoon: just read your comment on Indiegogo, congrats on your new Gemini May 23 13:21:51 :-D May 23 13:22:23 the Gemini looks really cool... May 23 13:22:51 still have to get used to the way you have to interact with the (Android) apps though... May 23 13:24:22 there are some keyboard issues with some apps, especially with the PgUp and PgDown keys which are not recognised by most apps May 23 13:24:43 actually I'm not so sure that Android is the best OS for this device May 23 13:24:47 btw you might find this useful: https://www.oesf.org/forum/index.php?showtopic=34768 May 23 13:25:27 probably not, though ATM is the best choice until Linux will be polished enough May 23 13:25:46 a lot of apps are a pain to use with the keyboard... I already am using the touch screen more than wanting to May 23 13:28:11 I can imagine... and using the touchscreen on a clamshell device isn't that confortable May 23 13:31:53 I also miss a fingerprint sensor... don't want everyone to access the device, but I also don't want complex logins each time... May 23 13:43:50 oh wow... kernel 3.18.41 ?? May 23 13:44:41 yes :( May 23 13:45:00 I believe a newer one is planned May 23 13:45:36 is there any coordinated place of development that you know of? May 23 13:45:47 or is it scattered all over the Net currently? May 23 13:49:05 there's the third party Gemian project: https://github.com/gemian May 23 13:49:31 in particular: https://github.com/gemian/gemini-keyboard-apps May 23 13:50:49 the official sources from Planet are here: https://github.com/dguidipc May 23 13:51:04 thanks, I'll have a look May 23 13:51:17 I'm not aware of any other repository May 23 13:52:07 the official development forum is here: https://developer.planetcom.co.uk/ May 23 13:52:43 and there's oesf, of course May 23 13:56:48 just logged in again on oesf... May 23 13:56:53 "Welcome back; your last visit was: Oct 23 2012, 10:16 AM" May 23 13:57:09 :-[ May 23 14:07:20 it was about time you logged in back :P May 23 14:07:51 thanksfully, oesf is now in a better shape than in the past **** BEGIN LOGGING AT Wed May 23 19:14:08 2018 May 23 20:54:46 greguu, ok, I have now finished with kexec/ubi vs. klibc May 23 20:55:22 I will push 4.14 for pxa then concentrate on kexecboot May 23 20:56:01 as for kernel, I'll wait for 4.17 **** ENDING LOGGING AT Thu May 24 03:00:03 2018
