Source and destionation was on the same disk. After a while, this happened: EIP: wake_up_forked_process+0xb8/0x18c EAX: 5a5a5a5a (suspicious) trace: do_fork kernel_thread pdflush kernel_thread_helper start_one_pdflush_thread pdflush __pdflush __pdflush background_writeout kernel_thread_helper The machine has 512M ram. It is a pentium IV 2.4GHz. The kernel is compiled with smp (hoping for hyperthreading but it haven't happened yet), preempt, devfs support (but devfs isn't mounted anywhere currently) and IDE driver for the SIS 5513. Both filesystems are ext2. The machine was in single-user mode at the time. I can reliably reproduce this if a more detailed oops will help in debugging. I have 2G of swap space on another IDE drive. compiled with gcc 2.95.4 from debian testing ide controller: 00:02.5 IDE interface: Silicon Integrated Systems [SiS] 5513 [IDE] I'm using dma, irq unmasking, 32-bit io and multiple sector transfers.
