Another way to lockup the system: dd if=/dev/zero of=/array/file bs=1024k count=10000
So now I didn't even use any code that came near ide (unless you take into account swapping ?)
The process ends again in a hangup: Jul 8 22:54:55 kalimero kernel: 3w-xxxx: scsi0: AEN drain failed, retrying. Jul 8 22:54:55 kalimero kernel: 3w-xxxx: scsi0: Controller errors, card not responding, check all cabling. Jul 8 22:54:55 kalimero kernel: 3w-xxxx: scsi0: Reset sequence failed. Jul 8 22:54:55 kalimero kernel: 3w-xxxx: scsi0: Unit #0: Command (f7c1cc00) timed out, resetting card.
Some interesting bits in the traces show the scsi being in a limbo: Jul 8 22:54:55 kalimero kernel: kupdated D 00000046 5052 7 1 8 6 (L-TLB) Jul 8 22:54:55 kalimero kernel: Call Trace: [call_reschedule_interrupt+5/11] [__down+192/352] [__down_failed+11/20] [.text.lock.super+279/518] [sync_old_buffers+102/336] Jul 8 22:54:55 kalimero kernel: [kupdate+418/480] [kupdate+0/480] [arch_kernel_thread+46/64] [kupdate+0/480] Jul 8 22:54:55 kalimero kernel: scsi_eh_0 R F7C64080 5760 8 1 9 7 (L-TLB) Jul 8 22:54:55 kalimero kernel: Call Trace: [tw_scsi_eh_abort+504/768] [scsi_try_to_abort_command+136/208] [__down_interruptible+373/416] [scsi_unjam_host+2045/2672] [scsi_error_handler+376/608] Jul 8 22:54:55 kalimero kernel: [arch_kernel_thread+46/64] [scsi_error_handler+0/608]
And of course the dd process is in state 'D'...
I should start browsing the sources for these scsi_* functions.
I would really like to know if I'm looking at a software or a hardware issue here.
