Sorry, I do not have latest kernel. Can someone confirm this on latest? At least bugtracker does not know about it, and to my understanding of source, should be still here.
dd if=/dev/zero bs=1M count=64 of=test mkfs.ext4 -F test echo -n " " | dd of=test bs=1 count=1 seek=297195 conv=notrunc mount -o loop test /mnt/test dmesg -c
On ubuntu natty with latest kernel, it seems, that fs/ext4/super.c:__save_error_info calls mod_timer before timer->function is set at end of fs/ext4/super.c:ext4_fill_super via sbi->s_err_report.function = print_daily_error_info;
This causes BUG_ON(!timer->function) in kernel/timer.c:__mod_timer Device is stuck, not usable any more.
Thanks
