Description Emmanuel Galanos 2001-05-06 12:47:47 EDT
I am testing the pre errata 2.4.3-2.14.19smp kernel. Extra memory is
being reserved than should be.

Memory: 93124k/98304k available (1326k kernel code, 4024k reserved, 104k data, 252k init, 0k highmem)

The e820 map looks ok (attached). Previous kernels also had this bug
(though I didn't notice till Henri pointed it out).

argh. Lynx does not support file uploads yet so I am adding the e802 map below.
BIOS-provided physical RAM map:
 BIOS-e820: 0000000000000000 - 000000000009fc00 (usable)
 BIOS-e820: 000000000009fc00 - 00000000000a0000 (reserved)

Can you either attach or email me the output of dmesg ?
