| |
Although 2.5.40 has been out for a while, I think I ought to post this bug as I haven't seen any other mention of it.
When I boot an 2.5.40 x86 kernel built with CONFIG_HIGHMEM64G, and with a 920kB initial ramdisk (2.2MB uncompressed), I get a kernel BUG() at highmem.c line 480, preceded by a message saying "scheduling with KM_TYPE 15 held!" The machine on which I experienced this problem has 1.25GB of RAM. The problem occurs with and without CONFIG_PREEMPT. All kernels that tried were SMP kernels running on a uniprocessor.
The problem does not occur if I build 2.5.40 with CONFIG_HIGHMEM4G or CONFIG_NOHIGMEM. So, it's probably not causing problems for many people, but I thought I should report it anyhow.
