I've an Acer 314T. I've installed RH 6.0 on it. Everythig works all right: all the application runs. The problem is that, quite often, even if i'm not doing nothing in particular (for example only playing mp3 files in console with mpg123) it crashes and a kernel panic appears with the error "could not allocate virtual memory at the address: xxxxxx" what can it be? i've seen at the linux on laptop page that my notebook works ok with kernel 2.0.x. Maybe it's a 2.2.x bug?
It sounds more like you may have a bad memory location or two that the 2.2.5 kernel (memory handling is different that in older kernels) has uncovered. You can troubleshoot this by typing mem=16m at the LILO boot: prompt which will narrow your memory space down to see if the problem goes away. You can experiment with the memory size to see where it goes away.
