Got the following journaling error on 2.4.5 SMP during shutdown ...

....

Unmounting local file systems.
journal_begin called without kernel lock held
kernel BUG at journal.c:423!
invalid operand: 0000
CPU1: 1
EIP: 0010:[<f8854140>]
EFLAGS: 00010286
eax: 0000001d ebx: f0951f2c ecx: 00000001 edx: 00000001

Process umount (pid: 265, stackpage=f0951000)

...

This bug only shows up on my SMP (2CPU) machine. It's been running fine on
1CPU non-smp machines.

Here's the difference for compiling ...

boston:root:/u2/src/linux> diff .config /root/src2/.config-2.4.5
54,55c54,55
< # CONFIG_NOHIGHMEM is not set
< CONFIG_HIGHMEM4G=y

> CONFIG_NOHIGHMEM=y
> # CONFIG_HIGHMEM4G is not set
57d56
< CONFIG_HIGHMEM=y
60,61c59,60
< CONFIG_SMP=y
< CONFIG_HAVE_DEC_LOCK=y

---
> # CONFIG_SMP is not set
> # CONFIG_X86_UP_IOAPIC is not set
68,69d66
< CONFIG_X86_IO_APIC=y
< CONFIG_X86_LOCAL_APIC=y






Thanks,
