Hi, I have a server that has long suffered from spontaneous reboots and random crashes. The problems seem to be partly SMP related since the machine is rock solid with a UP version of 2.6.11.11, but the same kernel compiled for SMP has issues. The server initially had 1 Intel Xeon CPU with HT and was very recently upgraded with an additional one (in the blind hope that the issues would be fixed). The kernel *seems* to die faster with 2 CPU's and a SMP kernel than it previously did with just one (HT) CPU and a SMP kernel. I've been trying newer kernels, such as 2.6.17.x, 2.6.18.x, 2.6.19-rc* (all SMP), hoping that the problem(s) would be fixed, but that does not seem to be the case. Recently I've been using netconsole and have lots of debug options enabled in the hope that I could capture some relevant info. Unfortunately nothing ever really made it to the remote log - except one little incomplete bit I got the other day (with 2.6.19-rc6) : do_IRQ: stack overflow: 492 That is all that made it to the log, but it does indicate that the problem might be stack-usage related. Since the kernel was compiled with 4K stacks, perhaps if it was changed to use 8K stacks it would stay up long enough for a complete dump to reach the logs. But, if 8K stacks really did help, it would be nice if the dumps still happened at the same point where they would have with 4K stacks. So, I changed STACK_WARN in include/asm/thread_info.h from (THREAD_SIZE/8) to(4608). This way I should get stack traces at the point where the kernel would be in trouble with a 4K stack but since it's actually using a 8K stack it should survive and let me capture the trace. I got more than I could ever have hoped for. I still got spontaneous reboots, but this time my remote log server captured tons of stack dumps. I've got far too many to send here (more than 2G) and most of them are identical anyway, so I'll just submit a few representative samples initially. Most of the traces include XFS functions and some also involve scsi and/or networking. This is the reason I'm submitting this to the XFS & netdev lists in addition to LKML. All of these traces were collected with 2.6.19-rc6 with the modification mentioned above. Hardware details and software environment info is at the end of the email. This is the most often captured trace : do_IRQ: stack overflow: 4416 [<c01039a7>] dump_trace+0x1e7/0x1fd [<c0103a67>] show_trace_log_lvl+0x1c/0x33 [<c0103a90>] show_trace+0x12/0x16 [<c0103b8f>]
