I have been trying all kernels after 3.3.7 (except for the 3.5 series) on my ix2-200 and have found that on every kernel 3.3.8, 3.4, 3.4.2, 3.4.4 =>3.4.7 and now even on 3.6 rc1 and the next dated today 17 august that when i use git for example: git clone git://git.videolan.org/x264 my system just crash's / hangs and even through the serial port i get no response. This also happens when i try to access a web interface for example the serviio java webui. The second issue i have noticed is that my raid 0 array hangs / pauses when being mounted at system startup. (for approximatly 30 seconds maybe more maybe less im not certain). But again on the 3.3.7 kernel there was no issue and no hang. If i return to 3.3.7 everything works fine with no other modifications to the os or kernels. I am using debian wheezy at the moment but also tried debian squeeze so it does not seem to be related to the specific linux version just the kernel.Can you bisect your problem? Doing that between 3.3.7 and 3.3.8 seems to be the obvious range to test. You can also try to enable the various debugging options like CONFIG_DETECT_HUNG_TASK CONFIG_PROVE_LOCKING CONFIG_DEBUG_ATOMIC_SLEEP CONFIG_MAGIC_SYSRQ or try https://lkml.org/lkml/2012/5/26/83.

For example: in 3.4.0 kernel i can use 'git clone git://git.videolan.org/x264' successfully. From 3.4.1 kernel on I can not use 'git clone git://git.videolan.org/x264' the system hangs / crashes with no output at all. the other issue the hang / stall while mounting my etx4 raid 0 is actualy much more recent than i remembered i have tested each kernel from 3.4.0 all the way to 3.4.9 with the config options enabled as sujested before and the stall first starts in kernel 3.4.8 and the following bug keeps popping up repeatedly until the raid is mounted and then anytime a disk is accessed it seems. I was certain it had been popping up before 3.4.8. The following is one of what pops up: BUG: sleeping function called from invalid context at include/linux/freezer.h:46 in_atomic(): 0, irqs_disabled(): 128, pid: 2166, name: minissdpd no locks held by minissdpd/2166. irq event stamp: 2081 hardirqs last enabled at (2080): [<c02f8dc8>] _raw_spin_unlock_irq+0x24/0x4c hardirqs last disabled at (2081): [<c00090cc>] ret_fast_syscall+0xc/0x38 softirqs last enabled at (0): [<c0016b38>] copy_process+0x3f8/0xfe8 softirqs last disabled at (0): [< (null)>] (null) [<c000eae4>] (unwind_backtrace+0x0/0xe0) from [<c000b5a0>] (do_signal+0x84/0x554) [<c000b5a0>] (do_signal+0x84/0x554) from [<c000bec0>] (do_notify_resume+0x18/0x60) [<c000bec0>] (do_notify_resume+0x18/0x60) from [<c0009120>] (work_pending+0x24/0x28)I think this is an unrelated issue that I think is fixed in later kernels. So I'd disable CONFIG_DEBUG_ATOMIC_SLEEP for further testing. Can you try a bisection, i.e. git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linu x. git cd linus git remote add -f stable git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux- st able.git git bisect v3.4.1 v3.4 and test if the kernel that is checked out then results in a freeze. Depending on the test result either do: git bisect good # i.e. problem doesn't occur or git bisect bad # problem is reproducible Repeat that until git points out the first bad commit and report that. Best regards Uwe -- Pengutronix e.K. | Uwe Kleine-K?nig | Industrial Linux Solutions | http://www.pengutronix.de/ |>I dont think it has as i have recently been building the latest 3.6 rc kernels while creating a patch for my nas and i had the same issue's on them. Thats what prompted me to actualy come to the mailing list with it. I have tried the 3.6-rc1 and the latest linux-next dated 17th of august.Im not sure if this is the right commit as i dont know what way it works but basically the very first commit caused the issue of me not being able to use git and when i typed the git bisect bad it said this: ownerx35 at ownerx35-VirtualBox:~/Desktop/linux$ git bisect bad Bisecting: 21 revisions left to test after this (roughly 5 steps) [774a93aa647f8939867c8ff956847bc63dd51cb3] usbhid: prevent deadlock during timeoutAfter calling git bisect bad it checks out files from a revision between the one currently checked and the one marked as good (imagine binary search). You have to compile and test resulting kernels and tell git whether they're good or bad until it tells you that it found the problematic commit. Best regards, Tomasz Figaquoted

this is odd i went back to the 3.4 kernel (which was working) from my earlier testing and which i can wrote to the nand on the device now has the same issue with the git clone? I tried the command just to make sure the kernel was working and nothing the nas just stopped like usual and after 3 rebuild of the kernel its still the same run the command and freeze. I think it seems that there is something bigger than the kernel causing the git problem i just decided out of curiosity to recompile a fresh 3.3.7 kernel which has been working perfectly and now git clone hangs the nas after being issued so perhaps its the compiler or OS that im compileing the kernels on perhaps something has gone wrong there. incase anyone wants to know im using ubuntu 11.10 in a virtual box vm.with the codesourcery arm toolchain dated 2012-03. and im sorry Tomasz but the last 2 messages arrording to mt gmail anyway were sent to the mailing list and not to you so i do not know how they went to you.
