Re: 2.4.22-pre3 and reiserfs boot problem

Having read the whole thread, I came up with a few ideas.

The following patches in -pre3 could perhaps have to do something with
your problems:
o (resend) collected semaphore fixes and semtimedop
o Fix potential IO hangs and increase interactiveness during heavy IO
o fix false sharing of mm info
o fix up semops and return, allow timedop
o mremap VM_LOCKED move_vma
o remove io_apic_modify - this doesnt work on some APICs
o small setup-pci cleanups

Since your hangs are not even traceable with SysRq, please try to boot
with nmi_watchdog=1 and if that doesn't work (dmesg will complain)
nmi_watchdog=2. About 15 seconds after the hang your box should print a
backtrace.

As a last resort you could mount the fs from UML.

I suggest you try the nmi_watchdog thing first.
