do_write_buffer(): software timeout

[Kasturi Raghunath]

Hi
  I am running 2.4.18 linux on my 8270 board with AMD29LV128ML flash chip. I
have patched May 27 2004 snapshot into my linux OS. JFFS2 and the MTD driver
works fine when there is no load on the CPU. But when I start sending wire
speed traffic on the ethernet port and simultaneously download a file to the
flash I get following error:

Any idea what could be the issue. Thanks in advance
