Hello, System: RedHat 6.2, AMD K6-2 500 Mhz, 64MB SDRAM (100Mhz), 512kb L2 cache. Kernel: 2.2.14-5.0 I am running a utility that reads the entire hard disk sector by sector twice, and compares the two buffers for each read. This is causing wierd behaviour; sometimes I get a segmentation fault, sometimes the system runs the init boot sequence again (if I run the program in runlevel 1, then it automatically starts the system in runlevel 3) !!! Also, I get errors using the 'llseek' and '_llseek' functions; sometimes they work correctly, and otherwise they return errno=22 (EINVAL). (my hard disk is a 2.1 GB Seagate drive, and the errors are returned with lseek offsets that are sometimes just 1 byte from the start of the disk == SEEK_SET !!!) Sometimes, due to heavy memory allocation, the kernel starts killing the system daemons, including the kernel threads, and the system just hangs. (I have a program that starts allocating memory infinitely, 1024 bytes at a time, in a for loop, and it too displays the same behaviour). The code is very simple ... I open the device file, read 512 bytes at a time, and continue to do so till the end of the hard disk is reached. Any ideas ? Thanks, ---------------------- Ashutosh S.
