Hi,
It seems that ioctl_by_bdev() in fs/block_dev.c has a problem.
When initrd is unmounted it can cause OOPS.
This problem occurs in recent ac patches.

change_root() in fs/super.c calls ioctl_by_bdev() in
fs/block_dev.c which does not set inode_fake.i_bdev.

i think DMA or PCI is not my solution , atleast :)
Thank you,
Hello,
I'm having the following problem, when trying to load usb-ohci as a module:
firmin:/usr/src/linux/drivers/usb# modprobe usb-ohci
/lib/modules/2.4.5/kernel/drivers/usb/usb-ohci.o: init_module: No such device

I agree.
I get around 4MB/s without and 35.75MB/s with...
hdparm -c3 -d1 -m16 /dev/hda
on a KT133 (A7V) and 45GB IB

Hi,
This was reported on the reiserfs list yesterday. Seems that the cleanup
applied late in 2.4.5-pre affected the locking of the umount process. This
was posted to fix the problem.

ramnfs has resource limits in -ac for a reason.

Its probably a bug - primarily it depends if the function is useful when
exported to non kernel code

Hi,
How is that supposed to work on systems without PCI? For now I have
defined
#define insl(port,buf,len) isa_insb(port,buf,(len)<<2)
#define outsl(port,buf,len) isa_outsb(port,buf,(len)<<2)
in asm-m68k/parport.h.

Hi,
while looking for the reason of a build failure of the ALSA libraries on
ARM [1] I discovered the following strange thing:
On some architectures a function is inside an "#ifdef __KERNEL__" in the
header file and on others not. Is there a reason for this or is this
inconsistency simply a bug?

Hi,
Today I downloaded kernel 2.4.5 and compiled it. The kernel worked fine
until
I tried to halt the computer. When trying to unmount the reiserfs
filesystems,
the system freezes with the following output:
journal_begin called without kernel lock held
kernel BUG at journal.c:423!

Bad idea. The kernel ACPI is not the most debugged, the ACPI in many BIOSes
is complete garbage and there isnt a lot you can do to debug them either.
APM is a definite better choice, at leas

Before returning to userspace do_IRQ just runs do_softirq by hand from C
