Hi to all of you ! I have this problem with the linux-2.4.5. When I want to shutdown the system I get this error message: // journal_begin called without kernel lock held kernel BUG at journal.c:423! invalid operand: CPU:1 EIP:0010:[] EFLAGS: 00010286 eax: 001d ebx:

multicast hash incorrect on big endian archs

I noticed that the multicast hash calculations assumed little endian byte ordering in the winbond-840 driver, and it seems that several other drivers are also affected: 8139too, epic100, fealnx, pci-skeleton, sis900, starfile, sundance, via-rhine, yellowfin perhaps

Linux networking and disk IO issues

I recently released a clusted storage system for Linux (the software in binary form and manual can be downloaded from www.northforknet.com). This software, you can create a highly available storage cluster out of standard PC hardware. During this work, we encountered a number of problems with

the value of PROC_CHANGE_PENALTY

as I understand, for i386 in Linux-2.2.x the default length of a quantum was 200ms, and in 2.4.x it had changed to 50ms ( according to the following 2.4.5 sched.c code: #if HZ < 200 #define TICK_SCALE(x) ((x) >> 2) ... #define NICE_TO_TICKS(nice) (TICK_SCALE(20-(nice))+1)

Reg mkdir syscall

Hi, Sorry to disturb you. Actually I had written a small file system(on 2.2.14 kernel) similar to RAMFS on 2.4 kernel. I am able to mount it but when I try to create directory under it, it gives EEXIST error saying" file already exists" but when I check the directory again that file gets
