Red Hat Bugzilla – Bug 198580
kernel hang "Starting udev:_" on Athlon SiS 730
Last modified: 2015-01-04 17:27:53 EST
Description of problem:
The kernel hangs with a hard freeze during init on a clone box with Athlon plain
CPU and Silicon Integrated Systems [SiS] 730 chipset. The VGA console shows
"Starting udev:_" where the '_' indicates that the cursor has stopped blinking.
Serial console shows no Oops. There is no response to any keyboard entries,
including <ctrl><alt><del>, <alt><sysrq>T, etc., even when appending "debug" or
"debug=7" to boot command line. The same symptom appears when appending
"single" option on the boot command line.
On the surface this seems to be a replay of:
bug #179601 which was caused by a bad kernel patch.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Hang "Starting udev:_"; no response after three minutes.
Last kernel known to work is 2.6.16-1.2289 ("2.6.17-rc6-bit7" ?)
I tried to perform git bisect. "git clone git://...", "git bisect start", "git
bisect bad 2.6.18" all worked. But "git bisect good 2.6.17" says "fatal: Need a
single revision" which stumps me. Suggestions?

At the last 4 ir 5 stages of "git bisect", the blink rate of the cursor on the
VGA console was erratic during "Starting udev: _". From about 2 Hz it would
slow to 1 Hz (or less) for 5 or 6 seconds, then resume at 2 Hz. Of course, the
bad bisects would slow to 0 Hz (no blinking; freeze).
if this still isn't fixed, could you bring it up on linux-kernel ?
The problem has disappered from kernel-2.6.17-1.2396.fc6 (and also 2405; 2401
