Re: [Jfs-discussion] 2.4.10 and jfs-1.0.7 = locked system

[Constantin L. <Con...@is...>]

Hi!

Should change subject to: 2.4.10 and jfs-1.0.8 = locked system

Again my system is locked up (seemingly after using the 
ioctl/FIBMAP call, but not reproducable)
The caps lock and scroll lock leds are blinking (they also did
last time but forgot to report that) and the system is dead
with no errors in the logs.

This time I did fsck.jfs -n but it didnot report any error.
Very strange as I cant mount my partition anymore. 

Output of fsck.jfs:
>fsck.jfs version 1.0.8, 17-Oct-2001
>Block size in bytes:  4096
>File system size in blocks:  263064

Mounting:

One thing I did not mention: I restricted my system
to 32MB of RAM (mem=32) and I shutdown my swap partitions. 
I dont think, that it matters, but you never know...

Any ideas?
