https://bugzilla.kernel.org/show_bug.cgi?id=115451 --- Comment #2 from Gaurav Sharma <gauravs.2010@xxxxxxxxx> --- Following is the system info : Host machine kernel version : 2.6.18-308.el5 Guest OS : Debian 3.2.0-4-686-pae KVM vesrion : QEMU PC emulator version 0.9.1 Following are the steps to re-create the issue : 1. Boot the guest OS using QEMU with KVM enabled. 2. lspci will list down the pci devices configured on the guest OS. 3. I have a some PCI device configured with bar0 memory. 4. modify the pcimem.c application to use call memset // This code is being modified to call memset to do a bulk write transaction case 'w': fprintf(stderr, "Before doing memset\n"); memset((virt_addr), 1, datalen); fprintf(stderr, "after doing memset\n"); break; 5. Call the pcimem application to write on bar0 memory. 6. It results in memset call in hang, and the application needs to be explicitly killed. I do not get the log message after memset call. -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
