Subject: Re: Fw: PROBLEM: Linux V. 2.6.3 panics with "Buffers at physical address >16Mb used for aha1542" at boot time

Dear James Bottomley, 

thank you very much for looking into the problem I have seen. 

Following to your kind suggestion, I have commented out the two "panic
(... Buffers and physical address > 16Mb ...)" lines in the aha1542.c
source and added "BUG();"-lines in their places. Booting the kernel
built afterwards resulted in a bunch of messages; I haven't been able to
read the first lines; this is what I could copy:

Please don't hesitate to contact me if I can be of any further help in
this matter.

Best wishes and regards, 

Ernst
