As a result some pending commands are timed out by the linux sym53c8xx driver, which sends SCSI Abort messages for the timed out commands. The SCSI Abort messages result in linux errors, which show up on the console and in /var/log/messages. e.g. sd 0:0:3:0: [sdd] tag#33 ABORT operation started scsi target0:0:3: control msgout: 80 20 47 d sd 0:0:3:0: ABORT operation complete. scsi target0:0:4: message d sent on bad reselection Now following a WAIT DISCONNECT Script instruction, and if there is no current command, check for a pending command on the queue and if one exists call lsi_reselect().

This tool can help if VMCoreInfo device/driver is absent in Windows VM and 'dump-guest-memory -w' is not available but dump can be created in ELF format. The tool works as follows: 1. Determine the system paging root looking at GS_BASE or KERNEL_GS_BASE to locate the PRCB structure and finds the kernel CR3 nearby if QEMU CPU state CR3 is not suitable. 2. Find an address within the kernel image by dereferencing the first IDT entry and scans virtual memory upwards until the start of the kernel. 3. Download a PDB matching the kernel from the Microsoft symbol store, and figure out the layout of certain relevant structures necessary for the dump. 4. Populate the corresponding structures in the memory image and create the appropriate dump header. ^ permalink raw reply [flat|nested] 21+ messages in thread
