Thanks for the suggestion Mark, here is what I've found out. When I run the trace after the IPL gets stuck I see the same four instructions repeated over and over again.
00013960' SLR 1F00 CC 2 00013962' CS BA01C000 0020F060 CC 1 00013966' BRM A744FFFB -> 0001395C' CC 1 -> 0001395C' DIAG 83000044 00000044 CC 1 When I look at the System.map created with the 2.4.18 kernel I can see the addresses fall within the range for '00013904 T die' I have compared the System.map files for the new and old kernel around the die address and I've noticed that there are some new instructions that were added. Not sure if it's important, but I wanted to point it out. On the old System.map I have: 00013240 T _zb_findmap 00013340 T die But on the new I have: 000132a0 T _zb_findmap 000133a0 T show_trace 000134dc T show_trace_task 00013514 T show_stack 000135d0 T show_registers 000137c0 T task_show_regs 00013904 T die Any ideas ??

Let that run for a bit to gather some information, and then stop it. Re-boot to your previous kernel, and compare the addresses in your trace to the System.map file that was generated by your kernel compile. That'll give you some hint as to where you are in the code. Then, you can re-post here with the information, possibly send it to [EMAIL PROTECTED] for some help.

We are running Suse 2.4.7 kernel on s/390 under z/VM. I need to update the kernel to level 2.4.18 to enable me to apply a patch to add ACL/EA support. For the meantime I'm just trying to upgrade to 2.4.18. I was able to successfully build the kernel. I then copied the image, System.map, ipleckd.boot files to a directory under /boot. To update the module dependancies I ran: 'depmod -a -F /boot/kernel-2.4.18/System.map 2.4.18'. I then ran 'zipl --image /boot/kernel-2.4.18/image' Both ran fine with no errors. After IPL'ing the instance it just gets stuck at 'POSIX conformance testing by UNIFIX'. Here is the output I get when connected to VM: hwc low level driver: can write messages hwc low level driver: can not read state change notifications hwc low level driver: can read commands hwc low level driver: can read priority commands Linux version 2.4.18 (root@files01d) (gcc version 2.95.3 20010315 (SuSE)) #1 SMP Mon Apr 29 08:43:42 CDT 2002 We are running under VM This machine has an IEEE fpu On node 0 totalpages: 32768 zone(0): 32768 pages. zone(1): 0 pages. zone(2): 0 pages.
