You still need to use "dmesg -s 100000" even if you specifie logbuf_len. Anyway, the data probably goes into /var/log/messages as well... If it

Of course, but there are still no other lines left...

I don't know how big I'd have to set the buffer, but I tried to set it to 2^25
(~33E6), but then the buffer seems to be reset to default? What's the limit?

See the attachment for the 1E5 buffer.

Still don't have the initialization part... Is there any way you could make your /var/log/messages file accessible via ftp or http?

Anyway, I also have a tiy patch to try out (attached, not tested/ not compiled). Please let me know how ifit makes any improvement.

Thank you.

Sorry for the delay.

No, unfortunately no improvement at all.

I tested with no special kernel option (no i8042.nodemux or similar).
