Hello! When booting, after loading the initrd and progressing with device detection, the kernel will usually stop continuing and instead repeatedly output (with varying type and page parameters): mptbase: ioc0: WARNING - Issuing Reset from mpt_config!!, doorbell=0x24000000 mptbase: ioc0: Attempting Retry Config request type 0x1, page 0x1, action 0 mptbase: ioc0: WARNING - Issuing Reset from mpt_config!!, doorbell=0x24000000 mptbase: ioc0: Initiating recovery It will not recover from that state. It appears that if I let the kernel continue until it reaches: WARNING: CPU: 1 PID: 17 at /usr/src/linux-3.12.8-gentoo/mm/page_alloc.c:2483 __alloc_pages_nodemask+0x460/0x1180() [...] scsi target2:0:0: mptspi: ioc0: dma_alloc_coherent for parameters failed (the SCSI devices will still not be accessible) and then hard-reset the machine, it will successfully boot on the next try. [4.] Kernel information [4.1.] Kernel version: The latest version that shows the problem is 3.12.8. [4.2.] Kernel .config file: Please find the config for 3.12.8-gentoo attached. The same issue appears with all vanilla kernels in the range I tested, so I am confident the Gentoo patches are not causing this. [5.] Most recent kernel version which did not have the bug: Both problems first appeared with Linux 3.9.10 after updating from 3.8.10. Since then I tested 3.10.8 and onward and 3.12.2 and newer and all suffer from this problem. [6.] Output of Oops: Please find the complete boot logs (and configs) for version 3.9.10 at following bugreports: https://bugzilla.kernel.org/show_bug.cgi?id=60566 https://bugzilla.kernel.org/show_bug.cgi?id=60567 The boot log for a hang situation with 3.12.8-gentoo is attached.
