Hello,
is there a known problem with the new kernel for CentOS 5.3?
Till today, my server works without any problems. But after updating to the new kernel 2.6.18-128.7.1.el5 the system freezes completely with no more access by keyboard or over network. The last message in /var/log/messages is 'Aug 25 14:07:41 weidenwinde kernel: hdg: dma_timer_expiry: dma status == 0x21'.
I have not change my hardware, have not change configuration and till this new kernel the system was running without any problems. The harddisks are younger than a year.
Is someone else this seeing?
regards Olaf

not me, I've got the new kernel on about 6 machines, and my laptop with no problems. What is the prev kernel you were running ? There were some major changes in the early 5.3 days thats caued some issues on some AMD based cpu's - however, nothing of this nature. Most of the issues I've seen and know that exist revolve around the acpi changes and xen.

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.

while we investigate this - can you open an issue report at bugs.centos.org ? that would be a good place to bring all this info together.
