Hi all (and developers in particular) I just got bitten by this Assertion. The one that starts as in the subject, and ends with: "!(((jh2bh(jh))->b_state & (1UL << BH_Lock)) != 0)" Google reminds me that it was mentioned a few times earlier this year, but I couldn't find any statement saying that it has been fixed. I got this in a 2.4.16 kernel, though the reports I found were 2.4.18. So my question is: has this been fixed yet? What seems to trigger it...

I had the following spat out by syslog on my (2.4.18-pre7-ac3) mailer / web server: Assertion failure in do_get_write_access() at transaction.c:611: "!(((jh2bh(jh))->b_state & (1UL << BH_Lock)) != 0)" One of its partitions froze hard--I've rebooted it, and I have an oops which the BUG() triggered which won't decode at the moment, but I'll sort that one out overnight. (It didn't make it to the filesystem, but I captured it from home.) I'll send the oops later,...

I have ext3 0.0.6b + 2.2.19 and cannot get ext3 to compile as a module. If I try to modularize it, or turn in off completely, the kernel build fails. Is there an easy fix for this, or is there something that I am missing? Thanks. Peter

When trying to build ext3 as a module, I get the follwing errors during the kernel link: /usr/bin/kgcc -D__KERNEL__ -I/home/brian/src/kernel-2.2.19-pre6mvd/linux-2.2.19pre6-kdb-ext3/include -c -o dummy_sym.o dummy_sym.c ld -m elf_i386 -T /home/brian/src/kernel-2.2.19-pre6mvd/linux-2.2.19pre6-kdb-ext3/arch/i386/vmlinux.lds -e stext arch/i386/kernel/head.o arch/i386/kernel/init_t ask.o -Map map
