If you know gdb decently well, tracing through a_Cache_process_dbuf() to see how it came up with that crazy length would be interesting.

Hello, I'm trying to post a message to the list, but I'm being rejected as a spammer, so I'm trying the "attachment method" :-) Thanks, S.

Why do you have to enter them character by character?

(I wonder how you found it) There's even a one-liner patch for the problem in the thread: http://lkml.org/lkml/2010/6/13/155 Have you tried it Dennis? -- Cheers Jorge.-

Do you mean dillo-2.0 is much faster than current repo even with a good kernel (i.e. no loobpack bug)?

If I can recall correctly, when kernel-2.6.30 was released, somebody submitted a few firmware patches in for a specific network adapter (whose driver is in the kernel). The patches were accepted into the 2.6.30 version breaking the driver at first, then later wake on LAN functions. >From what I saw from the patches, they almost rewrote the entire driver -- but the author did state he should have caught the bugs. The bugs have long since been fixed, but it does bring up an issue concerning kernel stability. However, I also realize if they try improving the quality of the kernel drivers, you might not see the patch integration until 2.7 or 2.8! Might also want to check out remote GDB to debug the kernel. -- Roger http://rogerx.freeshell.org/
