this is the second time the system freezes completely with kernel
2.6.18-128.7.1.el5 with the same error message 'kernel: hdg:
dma_timer_expiry: dma status == 0x21'. Now I am back under kernel
2.6.18-128.4.1.el5, no problems so far. My system:

The harddisk is connected to the Promise Technolog IDE Controller as a
master (ide2). Also there is a second identical harddisk connected to
this controller as a master (ide 1).
Over month there were no problems with previous kernels. After updating
to kernel 2.6.18-128.7.1.el5 the systems freezes for two times within a
few hours. And since booting into the old kernel, everything seems good
so far. In my opinion this is a kernel bug.
Two notebooks and two desktops are waiting here for the new kernel
update. I will do that now. Maybe the error is reproducible on
different hardware.
