loopback mount broken in 2.4.2-pre4
The subject gives just about all the information I have. :) If I try to mount an iso image via loopback while running 2.4.2-pre4, mount will hang forever. Downgrading to 2.4.1 seems to resolve the issue (haven't tried any previous -pre patches). --- Unsolicited advertisments to this address are not welcome. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
Kernel 2.4.2 - kernel BUG at apic.c:220!
When running 2.4.2 on a pentium 4, I get the following during boot: (any typos are due to me typing this in manually, off of what I see on the monitor connected to the P4. I've made sure the addresses are correct, at least... note that this happens with noapic passed as an option to the kernel as well) CPU: After generic, caps: 3febf9ff CPU: Common caps: 3febf9ff CPU: Intel(R) Pentium(R) 4 CPU 1300MHz stepping 07 Enabling fast FPU save and restore... done.

This is a single CPU system, not dual. The kernel is compiled for a single CPU system as well. Looking at .config, I notice that Processor family is set to Pentium-Pro/Celeron/Pentium-II. I could have *sworn* I changed that before compiling. Could that cause the problem I'm seeing? In any case, I'll try to get some time early next week to try the patch - this is, unfortunately, a work machine, and as such, needs to work, even if I go with 2.2.x. :) I'll let you know when I can try out the patch. > > or try the attached patch - it prints 2 additional debug lines. > > -- > Manfred > > > --- Unsolicited advertisments to this address are not welcome. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
