Nothing ever hits the disk (In interrupt handler - not syncing ...),
that's the reason why I had to install kmsgdump in the first place.
(Sidenote: a few days ago, I had the intent to install the lkcd kernel
patches, but gave up because of the time required to
patch/compile/install/setup correctly the kernel and userspace utilities
(not .deb of lkcd-utils available...)).
I suppose I could enlarge the kernel message log size, but the kmsgdup
documentation states:
If you have changed your messages buffer size (which is 16 kB by
default), you should modify the size in "include/asm/kmsgdump.h",
parameter LOG_BUF_LEN. Some people required 32 kB. But you shouldn't
exceed 60 kB since the dump is done in real mode (16 bits).
For kernel versions 2.5.6x and later, the LOG_BUF_LEN parameter is part
of the kernel .config file (LOG_BUF_SHIFT) so you don't need to modify
it at all.
--------------------------------- I you think 60kB would be enough to catch the first oops -- or if
the doc is outdated -- I can try this...
