site_archiver@lists.apple.com Delivered-To: darwin-kernel@lists.apple.com Importance: Normal Hi, My IOKit driver has provider Class IOPCIDevice. and Driver class is derived from IOSCSIParallelInteraceController. Running my driver on G5 PCI-X dual 1.8GHz system. When I load the driver using kextload -v myDriver.kext Randomly I get kernel panic at this point: ("pmap_unnest: Other processor (%d) did not see interruption request\n", i); This panic is totally occurs in random faction. Event if I restart the system and load the same binary I some times get the kernel panic and even some times it loads perfectly. I am not wiring down even 2-3Mbytes of memory for my PCI firmware. What can be the cause of this kernel panic?? I looked at the kernel panic back trace and none of the address falls in the my driver code. What steps or care should I take to avoid this pmap_unnest kernel panic? ----------------------------------------------------- panic(cpu 1): pmap_unnest: Other processor (0) did not see interruption request Latest stack backtrace for cpu 1: Backtrace: 0x000837BC 0x00083CA0 0x0001EDA4 0x00085D64 0x000600A0 0x000604EC 0x0002FE0C 0x0020ADB0 0x0020AC38 0x002405F4 0x00094300 0x00650079 Kernel loadable modules in backtrace (with dependencies): com.apple.iokit.IOHIDFamily(1.3.4)@0x640000 Proceeding back via exception chain: Exception state (sv=0x1DE52C80) PC=0x90034F4C; MSR=0x0000D030; DAR=0x16E5C004; DSISR=0x40000000; LR=0x9002C8EC; R1=0xBFFFF700; XCP=0x00000030 (0xC00 - System call) Kernel version: Darwin Kernel Version 7.3.1: Fri Mar 5 14:05:05 PST 2004; root:xnu/xnu-517.4.11.obj~1/RELEASE_PPC Regards, Parav Pandit _______________________________________________ Do not post admin requests to the list.
